ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED The environmental factors checked below would be potentially affected by this project, involving at least one impact that is “Less than Significant with Mitigation Incorporated” as indicated by the checklist on the following pages.  Aesthetics  Agriculture and Forest Resources  Air Quality  Biological Resources  Cultural Resources  Energy  Geology and Soils  Greenhouse Gas Emissions  Hazards and Hazardous Materials  Hydrology and Water Quality  Land Use and Planning  Mineral Resources  Noise  Population and Housing  Public Services  Recreation  Transportation  Tribal Cultural Resources  Utilities and Service Systems  Wildfire  Mandatory Findings of Significance Bubb Road Project Initial Study/Mitigated Negative Declaration 5 November 2020 D. DETERMINATION On the basis of this initial study: I find that the Proposed Project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the Proposed Project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the applicant. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the Proposed Project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a “potentially significant impact” or “potentially significant unless mitigated” on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. Signature Date Jeffrey Tsumura, Assistant Planner City of Cupertino Printed Name For Bubb Road Project Initial Study/Mitigated Negative Declaration 6 November 2020 E. BACKGROUND AND INTRODUCTION This Initial Study identifies and analyzes the potential environmental impacts of the Bubb Road Project (proposed project). The information and analysis presented in this document is organized in accordance with the order of the California Environmental Quality Act (CEQA) checklist in Appendix G of the CEQA Guidelines. Where the analysis provided in this document identifies potentially significant environmental effects of the project, mitigation measures are prescribed. The mitigation measures prescribed for environmental effects described in this Initial Study/Mitigated Negative Declaration (IS/MND) would be implemented in conjunction with the project, as required by CEQA. The mitigation measures would be incorporated into the project through project conditions of approval. The City would adopt findings and a Mitigation Monitoring/Reporting Program for the project in conjunction with approval of the project. On October 20, 2015, the City of Cupertino adopted an amended General Plan 1 and an associated Environmental Impact Report (EIR).2 The General Plan EIR is a program EIR, prepared pursuant to Section 15168 of the CEQA Guidelines (Title 14, California Code of Regulations, Sections 15000 et seq.). The General Plan EIR analyzed full implementation of the General Plan and identified measures to mitigate the significant adverse impacts associated with buildout of the General Plan. The proposed project would be consistent with the General Plan; therefore, in accordance with Section 15150 of the CEQA Guidelines (Section 21083.3 of the Public Resources Code), this IS/MND will tier from the previously certified EIR (SCH# 2014032007) prepared for the City’s General Plan where appropriate. F. PROJECT DESCRIPTION The following provides a description of the project site’s current location and setting, as well as the proposed project components and the discretionary actions required for the project. Project Location and Setting The project site consists of an approximately 32,316-square-foot (0.74-acre) property located at 11226 Bubb Road in the City of Cupertino, California (see Figure 1). The site is identified by Assessor’s Parcel Number (APN) 362-06-036 and is zoned Single-Family Residential with a minimum lot size of 7,500 (R1-7.5). The City’s General Plan designates the site as Low Density (1-5 DU/Ac.). The project site is bordered by Krzich Place to the north, Bubb Road to the west, existing one- and two-story, single-family residential homes to the east and south (see Figure 2). Additional single-family homes are located north and west of the site across Krzich Place and Bubb Road. The nearest major roadways, McClellan Road and Rainbow Drive, are located approximately 0.7-mile north of the site and 0.3-mile south of the site, respectively. The portion of Bubb Road between Rainbow Drive and McClellan Road is identified as a Minor Collector in the City’s General Plan and is a major route used by the residents in the South Monta Vista Area to access the neighborhood. 1 City of Cupertino.

Bubb Road Project Initial Study/Mitigated Negative Declaration 7 November 2020 Figure 1 Regional Location N Project Location Bubb Road Project Initial Study/Mitigated Negative Declaration 8 November 2020 Figure 2 Project Vicinity Map Project Site N Bubb Road Project Initial Study/Mitigated Negative Declaration 9 November 2020 The project site currently contains one single-family residence and associated structures (approximately 5,085 square feet total). Access to the residence is provided by a concrete driveway from Krzich Place. Vegetation on the site consists primarily of landscaping associated with the residence, including some trees and shrubs. Project Components The proposed project includes a request for the subdivision of a 32,316 gross square-foot lot into three lots, sized approximately 10,335 sf, 10,053 sf, and 11,928 sf (see Figure 3), which would allow for future redevelopment of the site with up to three single-family homes, each with up to one attached junior accessory dwelling unit (JADU) and one detached ADU. Demolition of the existing on-site structures would be required prior to final map recordation. In addition, the proposed project would include widening of the Krzich Place right-of-way by five feet along the project frontage, an approximately 943-sf area, which would be dedicated to the City. Future development of the site would likely include removal of several of the on-site trees and a concrete wall along Bubb Road. The removal of trees is not included as part of the proposed project, and, if required for future development, would be subject to a separate Tree Removal Permit if any of the trees are considered protected trees. While construction of homes is not proposed at this time, this environmental document analyzes the impacts associated with the potential for construction of homes at a later date following the proposed subdivision in order to provide a worst-case analysis. The single-family residences would likely include attached garages, and front or rear porch areas. Sewer and water service for future residences would be provided by the Cupertino Sanitary District and San Jose Water Company, respectively, by way of connections to existing sanitary sewer and water supply lines. New paved driveways would connect the garages of the three residences to the adjacent roadways. Lot A would be accessible by a driveway from Bubb Road, and Lots B and C would be accessible from driveways from Krzich Place (see Figure 4). In addition, future sidewalks would be installed along the adjacent roads, including a new detached sidewalk along Bubb Road. According to the preliminary Stormwater Control Plan prepared for the project site (see Figure 5), future residential development would incorporate three bioretention basins, one on each lot. If residential development occurs, it is anticipated that the bioretention basins would be sized to handle runoff from future impervious surfaces and landscaped areas. Roof runoff from the potential homes would be captured by a series of downspouts, deflected by splash blocks away from the buildings, and then flow to on-site landscaped areas and grassy swales to maximize infiltration before draining to the on-site bioretention basins. Discretionary Action Implementation of the proposed project would require City approval of a Tentative Parcel Map to subdivide the project site from one parcel into three parcels. Subsequent approvals would include discretionary permits for the construction of up to three single-family residences, which could include Two-Story Permits, Minor Residential Permits, Tree Removal Permits, and approval of a Final Subdivision Map.

ENVIRONMENTAL CHECKLIST The following Checklist contains the environmental checklist form presented in Appendix G of the CEQA Guidelines. The checklist form is used to describe the impacts of the proposed project. A discussion follows each environmental issue identified in the checklist. Included in each discussion are project-specific mitigation measures recommended, as appropriate, as part of the proposed project. For this checklist, the following designations are used: Potentially Significant Impact: An impact that could be significant, and for which no mitigation has been identified. If any potentially significant impacts are identified, an EIR must be prepared. Less Than Significant with Mitigation Incorporated: An impact that requires mitigation to reduce the impact to a less-than-significant level. Less-Than-Significant Impact: Any impact that would not be considered significant under CEQA relative to existing standards. No Impact: The project would not have any impact Bubb Road Project Initial Study/Mitigated Negative Declaration 14 November 2020 I. AESTHETICS. Would the project: Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less-Than- Significant Impact No Impact a. Have a substantial adverse effect on a scenic vista?     b. Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State scenic highway?     c. In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality?     d. Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area?     Discussion a,b. Examples of typical scenic vistas would include mountain ranges, ridgelines, or bodies of water as viewed from a highway, public space, or other area designated for the express purpose of viewing and sightseeing. In general, a project’s impact to a scenic vista would occur if development of the project would substantially change or remove a scenic vista. Given that the project site is currently developed and is located in a residential neighborhood, demolition of the on-site structures and potential future redevelopment of the site with up to three single-family homes would not significantly alter views of a scenic vista. Furthermore, according to the California Scenic Highway Mapping System, the project site is located approximately 3.35 miles north of the nearest State Scenic Highway, State Route (SR) 9, and approximately 1.8 miles south of Interstate 280 (I-280), an Eligible State Scenic Highway.3 Neither SR 9 or I-280 are visible from the project site. Based on the above discussion, the proposed project would not have a substantial adverse effect on a scenic vista and would not substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State Scenic Highway. Thus, no impact would occur related to such. c. Distinguishing between public and private views is important when evaluating changes to visual character or quality, because private views are views seen from privately-owned land and are typically associated with individual viewers, including views from private residences. Public views are experienced by the collective public, and include views of significant landscape features and along scenic roads. According to CEQA (Pub. Resources Code, § 21000 et seq.) case law, only public views, not private views, are protected under CEQA. Therefore, the focus in this section is on potential impacts to public views. 3 California Department of Transportation. California Scenic Highway Mapping System.

Bubb Road Project Initial Study/Mitigated Negative Declaration 15 November 2020 Sensitive public viewers in the surrounding area would primarily consist of motorists, pedestrians, and bicyclists travelling on Bubb Road and Krzich Place. Views of the project site from Bubb Road and Krzich Place currently consist of the existing on-site single-family residence, the existing on-site driveway, and various trees and shrubs. The project site is bordered on the east and south by two-story, single-family residences. The proposed project would include demolition of the existing on-site structures and removal of a majority of the on-site shrubs and trees. Implementation of the proposed project would allow for future redevelopment of the site with up to three single-family residences. Given that the site is already developed with a residential use, and the project would be consistent with the surrounding single-family residential development, the project would not substantially degrade the aesthetic character or quality of the site for motorists, pedestrians, and bicyclists travelling along Bubb Road and Krzich Place. In addition, the project would be consistent with the site’s existing zoning and General Plan land use designations. As such, changes to aesthetic character and quality associated with buildout of the site have been generally analyzed in the General Plan EIR. The General Plan EIR concludes that the bulk, mass, height and architectural character of new development are compatible with surrounding uses, thus impacts would be less than significant and without mitigation. Therefore, consistent with the General Plan, impacts related to degrading the existing visual character of the site and its surroundings would be less than significant. d. The project site is currently developed with a residential structure, and, thus, the site contains existing sources of light and glare associated with such, including, but not limited to, headlights on cars using the on-site driveway, exterior light fixtures, and interior light spilling through windows. In addition, the site is surrounded by existing residential development that currently generates similar light and glare in the area. Therefore, while potential future redevelopment of the project site with three residential homes would introduce new sources of light and glare from the site, such sources would be similar in nature to existing conditions and would not adversely affect day or nighttime views in the project area. Accordingly, a less-than-significant impact would occur related to light and glare. Bubb Road Project Initial Study/Mitigated Negative Declaration 16 November 2020 II.

Given the designation of the site as Urban and Built-Up Land, implementation of the proposed project and future development on the project site would not convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance to a non-agricultural use, or otherwise result in the loss of Farmland to non-agricultural use.

The City of Cupertino is located in the San Francisco Bay Area Air Basin (SFBAAB), which is under the jurisdiction of the Bay Area Air Quality Management District (BAAQMD). The SFBAAB is currently designated as a nonattainment area for the State and federal ozone, State and federal fine particulate matter 2.5 microns in diameter (PM2.5), and State respirable particulate matter 10 microns in diameter (PM10) ambient air quality standards (AAQS). The SFBAAB is designated attainment or unclassified for all other AAQS. It should be noted that on January 9, 2013, the U.S. Environmental Protection Agency (USEPA) issued a final rule to determine that the Bay Area has attained the 24- hour PM2.5 federal AAQS. Nonetheless, the Bay Area must continue to be designated as nonattainment for the federal PM2.5 AAQS until such time as the USEPA reviews and approves a redesignation request and a maintenance plan submitted by BAAQMD. In compliance with regulations, due to the nonattainment designations of the area, the BAAQMD periodically prepares and updates air quality plans that provide emission reduction strategies to achieve attainment of the AAQS, including control strategies to reduce air pollutant emissions through regulations, incentive programs, public education, and partnerships with other agencies. The current air quality plans are prepared in collaboration with the Metropolitan Transportation Commission (MTC) and the Association of Bay Area Governments (ABAG). The most recent federal ozone plan is the 2001 Ozone Attainment Plan, which was adopted on October 24, 2001 and approved by the California Air Resources Board (CARB) on November 1, 2001. The plan was submitted to the USEPA on November 30, 2001 for review, and was approved on July 7, 2003.6 The most recent State ozone plan is the 2017 Clean Air Plan (CAP), adopted on April 19, 2017. The 2017 CAP was developed as a multi-pollutant plan that provides an integrated control strategy to reduce ozone, PM, toxic air contaminants (TACs), and greenhouse gases (GHGs). Although a plan for achieving the State PM10 standard is not required, the BAAQMD has prioritized measures to reduce 6 U.S. Environmental Protection Agency. Air Actions, California.

Bubb Road Project Initial Study/Mitigated Negative Declaration 19 November 2020 both PM2.5 and PM10 in developing the control strategy for the 2017 CAP. The control strategy serves as the backbone of the BAAQMD’s current PM control program. The aforementioned air quality plans contain mobile source controls, stationary source controls, and transportation control measures to be implemented in the region to attain the State and federal AAQS within the SFBAAB. Adopted BAAQMD rules and regulations, as well as the thresholds of significance, have been developed with the intent to ensure continued attainment of AAQS, or to work towards attainment of AAQS for which the area is currently designated nonattainment, consistent with applicable air quality plans. The BAAQMD’s established significance thresholds associated with development projects for emissions of the ozone precursors – reactive organic gases (ROG) and oxides of nitrogen (NOx), as well as for PM10, and PM2.5, expressed in pounds per day (lbs/day) and tons per year (tons/yr), are listed in Table 1. By exceeding the BAAQMD’s mass emission thresholds for operational emissions of ROG, NOX, PM10, or PM2.5 a project would be considered to conflict with or obstruct implementation of the BAAQMD’s air quality planning efforts. Table 1 BAAQMD Thresholds of Significance Pollutant Construction Operational Average Daily Emissions (lbs/day) Average Daily Emissions (lbs/day) Maximum Annual Emissions (tons/year) ROG 54 54 10 NOx 54 54 10 PM10 (exhaust) 82 82 15 PM2.5 (exhaust) 54 54 10 Source: BAAQMD, CEQA Guidelines, May 2017. The proposed project would involve demolition of the on-site buildings and approval of a Tentative Subdivision Map, but does not include development of the site at this time. Nonetheless, the proposed project would allow for future development of up to three residential units on the project site. Thus, while the proposed project would not result in any direct emissions of criteria pollutants at this time, future development of the project site would involve emissions from construction and operation of up to three single-family residential units. Construction emissions associated with demolition of the on-site structures, as well as future construction-related and operational emissions associated with up to three single- family homes were quantified using the California Emissions Estimator Model (CalEEMod) software version 2016.3.2 - a Statewide model designed to provide a uniform platform for government agencies, land use planners, and environmental professionals to quantify air quality emissions, including GHG emissions, from land use projects. The model applies inherent default values for various land uses, including construction data, trip generation rates based on the Institute of Transportation Engineers (ITE) Trip Generation Manual, 9th Edition, vehicle mix, trip length, average speed, etc. In addition, the model assumes compliance with the 2016 Title 24 Standards. However, where project- specific information is available, such information should be applied in the model. Accordingly, the modeling assumed the following: Bubb Road Project Initial Study/Mitigated Negative Declaration 20 November 2020 • Construction would occur over an approximately five-month period;7 • All existing on-site structures would be demolished; • A total of approximately 0.74-acre of land would be disturbed during grading; and • A total of 591 cubic yards of soil would be exported during grading, including soil exported as part of the soil remediation activities discussed in Section VIII, Hazards and Hazardous Materials, of this IS/MND. All CalEEMod results are included as Appendix A to this IS/MND. It should be noted that at the time the modeling was conducted, June 2018 was the anticipated construction start date. Due to project delays, the timeframe for construction has substantially shifted. However, use of June 2018 as the date of initiation of construction represents a conservative approach to analysis. In particular, CalEEMod assumes that construction fleets will become more efficient in future years due to the implementation of statewide emissions reductions programs, such as the In-Use Off-Road Vehicle Regulation. Thus, construction of the potential homes beginning in the year 2018 would result in higher emissions than if the project were assumed to begin construction in the year 2020 or later. CalEEMod includes similar assumptions for operational emissions, with operational emissions generally decreasing into the future. By assuming an earlier initiation of construction activity, the first operational year of the project would also be assumed to occur earlier. As such, the use of June 2018 as an initiation date of construction activity allows for the conservative analysis of project-related emissions during both construction and operations. Furthermore, the project modeling assumed compliance with the 2016 Title 24 Standards. Construction would now be required to comply with the 2019 Title 24 Standards, which include more stringent efficiency requirements and would further reduce operational emissions. As such, the modeling presented below represents a conservative analysis, and all conclusions presented herein remain applicable. The estimated emissions associated with construction and operations of the project are presented and discussed in further detail below. A discussion of the proposed project’s contribution to cumulative air quality conditions is provided below as well. Construction Emissions According to the CalEEMod results, construction activities would result in maximum unmitigated criteria air pollutant emissions as shown in Table 2. As shown in the table, the construction emissions associated with demolition of the existing structures and future development of the site with up to three residences would be below the applicable thresholds of significance for ROG, NOX, PM10, and PM2.5. Fugitive emissions, defined as emissions that could not reasonably pass through a stack, chimney, vent, or other 7 The duration of construction activities assumed is based on default assumptions within the CalEEMod software. If the actual construction period is longer than assumed, then the daily project construction emissions would be slightly reduced compared to the daily construction emissions presented herein. Thus, the analysis provided herein is considered conservative. Bubb Road Project Initial Study/Mitigated Negative Declaration 21 November 2020 functionally equivalent opening (such as windblown dust),8 of PM10 and PM2.5 are also presented below for information purposes.

Although thresholds of significance for mass emissions of fugitive dust PM10 and PM2.5 have not been identified by the City of Cupertino or BAAQMD, because the region is in nonattainment for PM emissions (including exhaust and fugitive emissions) and fugitive PM emissions have the potential to contribute to health risks, the estimated fugitive dust emissions associated with the proposed project have been included for informational purposes. In addition, all projects within the jurisdiction of the BAAQMD are required to implement all of the BAAQMD’s Basic Construction Mitigation Measures, which include a number of measures aimed at reducing fugitive PM emissions. The BAAQMD’s Basic Construction Mitigation Measures are as follows: 1. All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. 2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. 3. All visible mud or dirt track-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. 4. All vehicle speeds on unpaved roads shall be limited to 15 mph. 5. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. 6. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to five minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations [CCR]). Clear signage shall be provided for construction workers at all access points. 8 U.S. Environmental Protection Agency.

The required implementation of the BAAQMD’s Basic Construction Mitigation Measures listed above would help to further minimize construction-related emissions. Because emissions associated with demolition of the existing structures and future development of the site with up to three residences would be below the applicable thresholds of significance, the proposed project would not be considered to result in a significant air quality impact during construction. Operational Emissions According to the CalEEMod results, future development of the site with up to three single- family residences would result in maximum unmitigated operational criteria air pollutant emissions as shown in Table 3. As shown in the table, the operational emissions associated with the proposed project would be below the applicable thresholds of significance. Because the operational emissions would be below the applicable thresholds of significance, the proposed project would result in a less-than-significant air quality impact during operations.

Cumulative Emissions Past, present and future development projects contribute to the region’s adverse air quality impacts on a cumulative basis. By nature, air pollution is largely a cumulative impact. A single project is not sufficient in size to, by itself, result in nonattainment of AAQS. Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project’s contribution to the cumulative impact is considerable, then the project’s impact on air quality would be considered significant. In developing thresholds of significance for air pollutants, BAAQMD considered the emission levels for which a project’s individual emissions would be cumulatively considerable. The thresholds Bubb Road Project Initial Study/Mitigated Negative Declaration 23 November 2020 of significance presented in Table 1 represent the levels at which a project’s individual emissions of criteria air pollutants or precursors would result in a cumulatively considerable contribution to the SFBAAB’s existing air quality conditions. If a project exceeds the significance thresholds presented in Table 1, the project’s emissions would be cumulatively considerable, resulting in significant adverse cumulative air quality impacts to the region’s existing air quality conditions. Because the emissions associated with the proposed project would be below the applicable thresholds of significance for both construction and operation, the project would not result in a cumulatively considerable contribution to the region’s existing air quality conditions. Conclusion As stated previously, the applicable regional air quality plans include the 2001 Ozone Attainment Plan and the 2010 CAP. According to BAAQMD, if a project would not result in significant and unavoidable air quality impacts after the application of all feasible mitigation, the project may be considered consistent with the air quality plans. Because the proposed project would result in emissions below BAAQMD’s thresholds of significance, the proposed project would not be considered to conflict with or obstruct the implementation of any regional air quality plans. Therefore, a less-than-significant impact would occur. c. Some land uses are considered more sensitive to air pollution than others, due to the types of population groups or activities involved. Heightened sensitivity may be caused by health problems, proximity to the emissions source, and/or duration of exposure to air pollutants. Children, pregnant women, the elderly, and those with existing health problems are especially vulnerable to the effects of air pollution. Sensitive receptors are typically defined as facilities where sensitive receptor population groups (i.e., children, the elderly, the acutely ill, and the chronically ill) are likely to be located. Accordingly, land uses that are typically considered to be sensitive receptors include residences, schools, playgrounds, childcare centers, retirement homes, convalescent homes, hospitals, and medical clinics. The nearest existing sensitive receptors to the project site would be the single-family residences located immediately to the south and east of the site. Additional single-family residences are located north and west of the site across Krzich Place and Bubb Road, respectively. The major pollutant concentrations of concern are localized carbon monoxide (CO) emissions and TAC emissions, which are addressed in further detail below. Localized CO Emissions Localized concentrations of CO are related to the levels of traffic and congestion along streets and at intersections. High levels of localized CO concentrations are only expected where background levels are high, and traffic volumes and congestion levels are high. Emissions of CO are of potential concern, as the pollutant is a toxic gas that results from the incomplete combustion of carbon-containing fuels such as gasoline or wood. CO emissions are particularly related to traffic levels. Bubb Road Project Initial Study/Mitigated Negative Declaration 24 November 2020 In order to provide a conservative indication of whether a project would result in localized CO emissions that would exceed the applicable threshold of significance, the BAAQMD has established screening criteria for localized CO emissions. According to BAAQMD, a proposed project would result in a less-than-significant impact related to localized CO emission concentrations if all of the following conditions are true for the project: • The project is consistent with an applicable congestion management program established by the county congestion management agency for designated roads or highways, regional transportation plan, and local congestion management agency plans; • The project traffic would not increase traffic volumes at affected intersections to more than 44,000 vehicles per hour; and • The project traffic would not increase traffic volumes at affected intersections to more than 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., tunnel, parking garage, underpass, etc.). The applicable Congestion Management Plan (CMP) for the project site is the Santa Clara Valley Transportation Authority (VTA) CMP.9 As discussed in the Transportation section of this IS/MND, the proposed project would not conflict with the VTA CMP. In addition, as noted throughout this IS/MND, the proposed project includes only demolition of the on-site buildings and approval of a Tentative Subdivision Map. However, this environmental analysis considers development of the site with up to three single-family residences. Such potential future residences would be anticipated to generate a total of 29 average daily trips (ADT). Given the relatively small number of trips that would be generated, the project would not substantially affect traffic volumes at intersections in the project vicinity. Furthermore, areas where vertical and/or horizontal mixing is limited due to tunnels, underpasses, or similar features do not exist in the project area. As such, based on the BAAQMD screening criteria, the proposed project would not be expected to result in substantial levels of localized CO at surrounding intersections or generate localized concentrations of CO that would exceed standards. TAC Emissions Another category of environmental concern is TACs. The CARB’s Air Quality and Land Use Handbook: A Community Health Perspective (Handbook) provides recommended setback distances for sensitive land uses from major sources of TACs, including, but not limited to, freeways and high traffic roads, distribution centers, and rail yards. The CARB has identified diesel particulate matter (DPM) from diesel-fueled engines as a TAC; thus, high volume freeways, stationary diesel engines, and facilities attracting heavy and constant diesel vehicle traffic are identified as having the highest associated health risks from DPM. Health risks associated with TACs are a function of both the concentration of emissions and the duration of exposure, where the higher the concentration and/or the 9 Santa Clara Valley Transportation Authority. 2013 Congestion Management Program. October 2013. Bubb Road Project Initial Study/Mitigated Negative Declaration 25 November 2020 longer the period of time that a sensitive receptor is exposed to pollutant concentrations would correlate to a higher health risk. The proposed project would not involve any land uses or operations that would be considered major sources of TACs, including DPM. As such, the proposed project would not generate any substantial pollutant concentrations during operations. However, short- term, construction-related activities could result in the generation of TACs, specifically DPM, from on-road haul trucks and off-road equipment exhaust emissions. Nevertheless, construction is temporary and occurs over a relatively short duration in comparison to the operational lifetime of the proposed project. All construction equipment and operation thereof would be regulated per the In-Use Off-Road Diesel Vehicle Regulation, which is intended to help reduce emissions associated with off-road diesel vehicles and equipment, including DPM. Project construction would also be required to comply with all applicable BAAQMD rules and regulations, particularly associated with permitting of air pollutant sources. In addition, construction activity (except for street construction) would be limited to daytime hours per Section 10.48.053 of the City’s Municipal Code. Because construction equipment on-site would not operate for long periods of time and would occur on a relatively small scale, associated emissions of DPM would be minimal. Due to the temporary nature of construction and the relatively short duration of potential exposure to associated emissions, sensitive receptors in the area would not be exposed to pollutants for a permanent or substantially extended period of time. Therefore, construction of the proposed project would not be expected to expose nearby sensitive receptors to substantial pollutant concentrations. Conclusion Based on the above, the proposed project would not expose any sensitive receptors to substantial concentrations of localized CO or TACs from construction or operation. Therefore, the proposed project would result in a less-than-significant impact related to the exposure of sensitive receptors to substantial pollutant concentrations. d. Emissions of concern include those leading to odors, emission of dust, or emissions considered to constitute air pollutants. Air pollutants have been discussed in sections “a” through “c” above. Therefore, the following discussion focuses on emissions of odors and dust. Per the BAAQMD CEQA Guidelines, odors are generally regarded as an annoyance rather than a health hazard.10 Manifestations of a person’s reaction to odors can range from psychological (e.g., irritation, anger, or anxiety) to physiological (e.g., circulatory and respiratory effects, nausea, vomiting, and headache). The presence of an odor impact is dependent on a number of variables including: the nature of the odor source; the frequency of odor generation; the intensity of odor; the distance of odor source to sensitive receptors; wind direction; and sensitivity of the receptor. 10 Bay Area Air Quality Management District. California Environmental Quality Act Air Quality Guidelines [pg. 7-1. May 2017. Bubb Road Project Initial Study/Mitigated Negative Declaration 26 November 2020 Due to the subjective nature of odor impacts, the number of variables that can influence the potential for an odor impact, and the variety of odor sources, quantitative methodologies to determine the presence of a significant odor impact do not exist. Typical odor-generating land uses include, but are not limited to, wastewater treatment plants, landfills, and composting facilities. The proposed project would not introduce any such land uses. Residential land uses, such as the potential future single-family homes, are not typically associated with objectionable odors. Construction activities often include diesel-fueled equipment and heavy-duty trucks, which could create odors associated with diesel fumes that may be considered objectionable. However, as discussed above, construction activities would be temporary, and operation of construction equipment would be restricted to daytime hours per the City’s Municipal Code. Project construction would also be required to comply with all applicable BAAQMD rules and regulations, particularly associated with permitting of air pollutant sources. The aforementioned regulations would help to minimize air pollutant emissions, as well as any associated odors. Accordingly, substantial objectionable odors would not be expected to occur during construction activities. It should be noted that BAAQMD regulates objectionable odors through Regulation 7, Odorous Substances, which does not become applicable until the Air Pollution Control Officer (APCO) receives odor complaints from ten or more complainants within a 90-day period. Once effective, Regulation 7 places general limitation on odorous substances and specific emission limitations on certain odorous compounds, which remain effective until such time that citizen complaints have not been received by the APCO for one year. The limits of Regulation 7 become applicable again when the APCO receives odor complaints from five or more complainants within a 90-day period. Thus, although not anticipated, if odor complaints are made after the proposed project is developed, the BAAQMD would ensure that such odors are addressed and any potential odor effects reduced to less than significant. As noted previously, all projects under the jurisdiction of BAAQMD are required to implement the BAAQMD’s Basic Construction Mitigation Measures. The measures would act to reduce construction-related dust by ensuring that haul trucks with loose material are covered, reducing vehicle dirt track-out, and limiting vehicle speeds within project site, among other methods, which would ensure that construction activities associated with the proposed project does not result in substantial emissions of dust. For the aforementioned reasons, construction and operation of the proposed project would not result in emissions (such as those leading to odors) adversely affecting a substantial number of people, and a less-than-significant impact would result.

The site is currently developed with a residential use and is highly disturbed as a result. Vegetation on the site consists of landscaping associated with the residence, including some grass and shrubs, as well as several trees. The project site does not contain any aquatic or riparian habitat. Raney Planning & Management, Inc. conducted a search of published records of special- status plant and wildlife species using the California Natural Diversity Database (CNDDB). The intent of the database review was to identify documented occurrences of special-status species in the vicinity of the project area, to determine their locations relative to the project site, and to evaluate their habitat requirements. The Cupertino Quad was used as the search area. The CNDDB query results indicate 4 special-status plant and 10 special- status wildlife species that are known to occur within the project vicinity. However, due to the highly-disturbed nature of the project site, the requisite habitat types for all of the identified special-status species do not occur on-site. For example, the species that require aquatic, woodland, chaparral, upland forest, or proximate open grassland habitat, would Bubb Road Project Initial Study/Mitigated Negative Declaration 28 November 2020 not occur on-site because those habitats do not occur on-site or in the immediate project vicinity. While special-status species would not occur on-site, migratory birds have the potential to nest within the on-site trees and shrubs. Birds and their nests are protected under California Fish and Game Code (Sections 3503, 3503.5, 3513), and the Migratory Bird Treaty Act (MBTA). If the proposed project includes the removal of trees during construction, impacts to nesting migratory birds could occur. Therefore, the proposed project could have a substantial adverse effect, either directly or through habitat modifications, on species identified as a candidate, sensitive, or special-status in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service, and a potentially significant impact could result. Mitigation Measure(s) Implementation of the following mitigation measure would reduce the above impact to a less-than-significant level. IV-1.Nests of raptors and other birds shall be protected when in active use, as required by the federal Migratory Bird Treaty Act and the California Fish and Game Code. The construction contractor shall indicate the following on all construction plans, if construction activities and any required tree removal occur during the breeding season (February 1 and August 31). Preconstruction surveys shall: •Be conducted by a qualified biologist prior to tree removal or grading, demolition, or construction activities. Note that preconstruction surveys are not required for tree removal or construction, grading, or demolition activities outside the nesting period. •Be conducted no more than 14 days prior to the start of tree removal or construction. •Be repeated at 14-day intervals until construction has been initiated in the area after which surveys can be stopped. •Document locations of active nests containing viable eggs or young birds. Protective measures for active nests containing viable eggs or young birds shall be implemented under the direction of the qualified biologist until the nests no longer contain eggs or young birds. Protective measures shall include: •Establishment of clearly delineated exclusion zones (i.e., demarcated by identifiable fencing, such as orange construction fencing or equivalent) around each nest location as determined by the qualified biologist, taking into account the species of birds nesting, their tolerance for disturbance and proximity to existing Bubb Road Project Initial Study/Mitigated Negative Declaration 29 November 2020 development. In general, exclusion zones shall be a minimum of 300 feet for raptors and 75 feet for passerines and other birds. • Monitoring active nests within an exclusion zone on a weekly basis throughout the nesting season to identify signs of disturbance and confirm nesting status. • An increase in the radius of an exclusion zone by the qualified biologist if project activities are determined to be adversely affecting the nesting birds. Exclusion zones may be reduced by the qualified biologist only in consultation with California Department of Fish and Wildlife. • The protection measures shall remain in effect until the young have left the nest and are foraging independently or the nest is no longer active. b,c. The project site is currently developed with a residential use, and, thus, is highly disturbed. The site does not contain any aquatic features or riparian habitat, and sensitive plant communities, including wetlands, do not exist on or near the site. As a result, the proposed project would not have a substantial adverse effect on riparian habitat, sensitive natural communities, or state or federally protected wetlands. Thus, no impact would occur. d. The project site is surrounded by existing development and is not linked to any open space areas through which wildlife movement would occur. The project does not contain streams or other waterways that could be used by migratory fish or as a wildlife corridor for other wildlife species. As such, the project would not interfere substantially with the movement of any resident or migratory fish or wildlife species or with established resident or migratory wildlife corridors, or impede the use of wildlife nursery sites. Thus, no impact would occur. e. As noted previously, the removal of trees is not included as part of the proposed project. However, based on the future plans for the site, development on the project site with up to three single-family residences would likely involve the removal of several on-site trees. If the trees to be removed are determined to be protected trees pursuant to Section 14.18.050 of the City’s Municipal Code, a Tree Removal Permit must be obtained from the City’s Community Development Department. The information required when submitting a Tree Removal Permit application, includes, but is not limited to, the following: • A drawing outlining the location of the tree(s) and proposed tree replacements. • A written explanation of why the tree(s) should be removed. In conjunction with the tree removal permit, the City would impose tree replacement standards or in-lieu fees pursuant to Section 14.18.160 of the Municipal Code. Furthermore, per Section 14.18.060 of the Municipal Code, the project applicant would be required to adopt a maintenance plan for any protected trees that would be retained as part of the project. Compliance with Chapter 14.18 of the City’s Municipal Code, as described above, would ensure that any future development on the project site would not conflict with the City’s tree preservation policies and ordinances. Therefore, the project would not Bubb Road Project Initial Study/Mitigated Negative Declaration 30 November 2020 conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance, and a less-than-significant impact would occur. f. In 2012, the County of Santa Clara adopted the Santa Clara Valley Habitat Plan (SCVHP), which provides a framework for promoting the protection and recovery of natural resources, including endangered species within unincorporated portions of the County and the cities of Gilroy, Morgan Hill, and San Jose. However, the City of Cupertino is not included in the area covered by the SCVHP. Therefore, the project site is not located in an area with an approved Habitat Conservation Plan/Natural Community Conservation Plan (HCP/NCCP), or local, regional, or State habitat conservation plan, and no impact would occur regarding a conflict with the provisions of such a plan. Bubb Road Project Initial Study/Mitigated Negative Declaration 31 November 2020 V. CULTURAL RESOURCES.

Cause a substantial adverse change in the significance of a unique archaeological resource pursuant to Section 15064.5?     c. Disturb any human remains, including those interred outside of dedicated cemeteries.     Discussion a. Historical resources are features that are associated with the lives of historically-important persons and/or historically-significant events, or that embody the distinctive characteristics of a type, period, region, or method of construction. Examples of typical historical resources include, but are not limited to, buildings, farmsteads, rail lines, bridges, and trash scatters containing objects such as colored glass and ceramics. As discussed previously, the project site currently contains a single-family residence and associated structures. In order to determine whether the on-site structures constitute historical resources, the structures were evaluated using the California Register of Historic Resources (CRHR) and National Register of Historic Places (NRHP) eligibility criteria, as presented below. CRHR Criteria The CRHR eligibility criteria include the following: (1) It is associated with events that have made a significant contribution to the broad patterns of local or regional history, or the cultural heritage of California or the U.S.; (2) It is associated with the lives of persons important to local, California, or national history; (3) It embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of a master or possesses high artistic values; or (4) It has yielded, or has the potential to yield, information important to the prehistory or history of the local area, California, or the nation. In addition, the resource must retain integrity. Integrity is evaluated with regard to the retention of location, design, setting, materials, workmanship, feeling, and association. NRHP Criteria The NRHP eligibility criteria include the following: “The quality of significance in American history, architecture, archaeology, and culture is present in districts, sites, buildings, structures, and objects of state and local importance that possess aspects of integrity of location, design, setting, materials, workmanship, feeling, association, and Bubb Road Project Initial Study/Mitigated Negative Declaration 32 November 2020 (a) is associated with events that have made a significant contribution to the broad patterns of our history; (b) is associated with the lives of a person or persons significance in our past; (c) embodies the distinctive characteristics of a type, period or method of construction, or represents the work of a master, or possesses high artistic value, or represents a significant and distinguishable entity whose components may lack individual distinction; or (d) has yielded or may be likely to yield information important in prehistory or history. In addition, the resource must be at least 50 years old, except in exceptional circumstances. Evaluation According to the Phase I Environmental Site Assessment (ESA) prepared for the project site, the on-site residence was constructed circa 1955 and an associated pool house was constructed circa 2013. Because the existing pool house is less than 50 years old, the structure does not meet the criteria to qualify as a historic resource. The on-site residence is greater than 50 years old and, thus, must be further evaluated using the remaining eligibly criteria. The residence is not known to be associated with any significant historical events, have been occupied or owned by any persons important to local, State, or national history, or associated with the lives of a person or persons of significance. In addition, the on-site residence is similar to the other surrounding single-family residences in the area. Thus, the residence does not embody the distinctive characteristics of a type, period or method of construction, represent the work of a master, possess high artistic value, or represent a significant and distinguishable entity whose components may lack individual distinction. Furthermore, according to the Phase I and Phase II ESAs, improvements to the residence were made in 1987 and in 1998, including a new furnace, mechanical work, and an addition or remodel. While the residence may retain integrity of location and some integrity of design, the house has undergone modifications since original construction in 1955. As such, the property overall would not be considered to have retained integrity of design, material, workmanship, or feeling, and would not be considered to possess sufficient physical integrity necessary to reflect historical significance. Similarly, due to the improvements made to the home since 1955, including the addition of the pool house, the structure would not be likely to yield information important to the prehistory or history of the local area, California, or the nation. Conclusion Based on the above, the on-site structures would not be considered eligible for consideration as historical resources per the CRHR or NRHP eligibility criteria, and, thus, would not be considered historical resources. Therefore, the project would not cause a substantial adverse change in the significance of a historical resource, and a less-than- significant impact would occur. Bubb Road Project Initial Study/Mitigated Negative Declaration 33 November 2020 b,c. The project site is currently developed with a residential structure, and, thus, is highly disturbed. In addition, the site is located within a residential neighborhood. Due to the disturbed nature of the site and the surrounding area, the discovery of underlying archeological and/or tribal resources is not expected. However, unknown archaeological resources, including human bone, have the potential to be uncovered during ground- disturbing construction activities at the project site. In compliance with State law (Section 7050.5 of the Health and Safety Code and Section 5097.94 of the Public Resources Code), as well as the City’s standard conditions of approval, in the event human remains are encountered during grading and construction, all work within 50 feet of the find would be stopped, and the Santa Clara County Coroner’s office would be notified. If the remains are determined to be Native American, the Coroner would notify the Native American Heritage Commission to identify the “Most Likely Descendant” (MLD). The City of Cupertino, in consultation with the MLD, would then prepare a plan for treatment, study, and re-internment of the remains. Therefore, given the low likelihood of encountering resources, and the proposed project’s compliance with the City’s standard conditions of approval regarding cultural resources, the project would not cause a substantial adverse change in the significance of a unique archaeological resource pursuant to CEQA Guidelines Section 15064.5 or disturb human remains, including those interred outside of formal cemeteries. Therefore, impacts would be considered less than significant. Bubb Road Project Initial Study/Mitigated Negative Declaration 34 November 2020 VI. ENERGY. Would the project: Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less-Than- Significant Impact No Impact a. Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation?     b. Conflict with or obstruct a state or local plan for renewable energy or energy efficiency?     Discussion a,b. The main forms of available energy supply are electricity, natural gas, and oil. A description of the California Green Building Standards Code and the Building Energy Efficiency Standards, with which the proposed project would be required to comply, as well as discussions regarding the proposed project’s potential effects related to energy demand during construction and operations are provided below. California Green Building Standards Code The California Green Building Standards Code, otherwise known as the CALGreen Code (CCR Title 24, Part 11), is a portion of the California Building Standards Code (CBSC), which became effective with the rest of the CBSC on January 1, 2020. The purpose of the CALGreen Code is to improve public health, safety, and general welfare by enhancing the design and construction of buildings through the use of building concepts having a reduced negative impact or positive environmental impact and encouraging sustainable construction practices. The provisions of the code apply to the planning, design, operation, construction, use, and occupancy of every newly constructed building or structure throughout California. Requirements of the CALGreen Code include, but are not limited to, the following measures: • Compliance with relevant regulations related to future installation of Electric Vehicle charging infrastructure in residential and non-residential structures; • Indoor water use consumption is reduced through the establishment of maximum fixture water use rates; • Outdoor landscaping must comply with the California Department of Water Resources’ Model Water Efficient Landscape Ordinance (MWELO), or a local ordinance, whichever is more stringent, to reduce outdoor water use; • Diversion of 65 percent of construction and demolition waste from landfills; • Mandatory periodic inspections of energy systems (i.e., heat furnace, air conditioner, mechanical equipment) for nonresidential buildings over 10,000 square feet to ensure that all are working at their maximum capacity according to their design efficiencies; • Mandatory use of low-pollutant emitting interior finish materials such as paints, carpet, vinyl flooring, and particle board; and Bubb Road Project Initial Study/Mitigated Negative Declaration 35 November 2020 • For some single-family and low-rise residential development developed after January 1, 2020, mandatory on-site solar energy systems capable of producing 100 percent of the electricity demand created by the residence(s). Certain residential developments, including those developments that are subject to substantial shading, rendering the use of on-site solar photovoltaic systems infeasible, are exempted from the foregoing requirement. Building Energy Efficiency Standards The 2019 Building Energy Efficiency Standards is a portion of the CBSC, which expands upon energy-efficiency measures from the 2016 Building Energy Efficiency Standards. The 2019 Building Energy Efficiency Standards are in effect for building permit applications submitted after January 1, 2020. The 2019 standards provide for additional efficiency improvements beyond the current 2016 standards. For residential buildings, compliance with the 2019 standards will use approximately seven percent less energy due to energy efficiency measures compared to homes built under the 2016 standards. Once rooftop solar electricity generation is factored in, homes built under the 2019 standards will use approximately 53 percent less energy than those under the 2016 standards.11 Cupertino Reach Codes According to the Bay Area Regional Energy Network (BayREN), local governments may adopt “reach codes,” which are more restrictive local amendments to the Building Energy Efficiency Standards or the CALGreen Code. In December of 2019, the City of Cupertino adopted a reach code, in which Chapter 16.54, Energy Code, of the City’s Municipal Code was replaced with a more stringent version of the Building Energy Efficiency Standards. Under the City’s reach code, all newly constructed residential and non-residential buildings would be required to be built all-electric, meaning that the buildings would not have natural gas or propane infrastructure installed, and that electricity shall be the sole source of energy for all space heating, water heating, cooking appliances, and clothes drying appliances. ADUs and Junior ADUs, along with non-residential kitchens, are exempt from the all- electric requirement. In addition, the City’s electric vehicle (EV) reach code requires that all new development projects, except for ADUs and Junior ADUs, include EV charging stations. The all-electric reach code and the EV reach code measures were designed to result in the greatest impact on reducing emissions from energy usage in newly constructed buildings in Cupertino. The project would be required to comply with all applicable provisions if the City’s reach codes. As such, the potential future single-family residences would be required to be all- electric and include EV charging systems. Compliance with the City’s reach code would further ensure that the project and any associated future development would not result in any substantially adverse effects related to energy. 11 California Energy Commission. Title 24 2019 Building Energy Efficiency Standards FAQ. November 2018. Bubb Road Project Initial Study/Mitigated Negative Declaration 36 November 2020 Construction Energy Use Demolition associated with the proposed project would involve on-site energy demand and consumption related to use of oil in the form of gasoline and diesel fuel for construction worker vehicle trips, hauling and materials delivery truck trips, and operation of off-road construction equipment. In addition, during construction of the potential future residences, diesel-fueled portable generators may be necessary to provide additional electricity demands for temporary on-site lighting, welding, and for supplying energy to areas of the site where energy supply cannot be met via a hookup to the existing electricity grid. Project construction would not involve the use of natural gas appliances or equipment. Even during the most intense period of construction, due to the different types of construction activities (e.g., site preparation, grading, building construction), only portions of the project site would be disturbed at a time, with operation of construction equipment occurring at different locations on the project site, rather than a single location. In addition, all construction equipment and operation thereof would be regulated by the CARB In-Use Off-Road Diesel Vehicle Regulation. The In-Use Off-Road Diesel Vehicle Regulation is intended to reduce emissions from in-use, off-road, heavy-duty diesel vehicles in California by imposing limits on idling, requiring all vehicles to be reported to CARB, restricting the addition of older vehicles into fleets, and requiring fleets to reduce emissions by retiring, replacing, or repowering older engines, or installing exhaust retrofits. The In-Use Off-Road Diesel Vehicle Regulation would subsequently help to improve fuel efficiency and reduce GHG emissions. Technological innovations and more stringent standards are being researched, such as multi-function equipment, hybrid equipment, or other design changes, which could help to reduce demand on oil and emissions associated with construction. The CARB has prepared the 2017 Climate Change Scoping Plan Update (2017 Scoping Plan),12 which builds upon previous efforts to reduce GHG emissions and is designed to continue to shift the California economy away from dependence on fossil fuels. Appendix B of the 2017 Scoping Plan includes examples of local actions (municipal code changes, zoning changes, policy directions, and mitigation measures) that would support the State’s climate goals. The examples provided include, but are not limited to, enforcing idling time restrictions for construction vehicles, utilizing existing grid power for electric energy rather than operating temporary gasoline/diesel-powered generators, and increasing use of electric and renewable fuel-powered construction equipment. The In-Use Off-Road Diesel Vehicle Regulation described above, with which the proposed project must comply, would be consistent with the intention of the 2017 Scoping Plan and the recommended actions included in Appendix B of the 2017 Scoping Plan. Based on the above, the temporary increase in energy use occurring during demolition activities and future construction associated with the proposed project would not result in a significant increase in peak or base demands or require additional capacity from local or regional energy supplies. In addition, the proposed project would be required to comply with all applicable regulations related to energy conservation and fuel efficiency, which would help to reduce the temporary increase in demand. 12 California Air Resources Board. The 2017 Climate Change Scoping Plan Update. January 20, 2017. Bubb Road Project Initial Study/Mitigated Negative Declaration 37 November 2020 Operational Energy Use The proposed project would include demolition and subdivision of the project site. However, as noted throughout this IS/MND, up to three single-family residences could be constructed upon subdivision of the site. Energy use associated with operation of the future residences would be typical of residential developments, requiring electricity for interior and exterior building lighting, heating, ventilation, and air conditioning (HVAC), electronic equipment, machinery, refrigeration, appliances, security systems, and more. Per the City’s reach code, the residences would be all-electric, and would not include the provision of any natural gas infrastructure. Maintenance activities during operations, such as landscape maintenance, would involve the use of electric or gas-powered equipment. In addition to on-site energy use, the potential homes would result in transportation energy use associated with vehicle trips generated by future residents. The proposed project would be subject to all relevant provisions of the most recent update of the CBSC and the City’s reach code. Adherence to the most recent CBSC and the City’s reach code would ensure that the proposed structures would consume energy efficiently through the incorporation of features such as electric appliances, door and window interlocks, direct digital controls for HVAC systems, and high efficiency outdoor lighting. Required compliance with the CBSC would ensure that the building energy use associated with any potential future residences would not be wasteful, inefficient, or unnecessary. In addition, electricity supplied to future residences by PG&E would comply with the State’s Renewable Portfolio Standard (RPS), which requires investor-owned utilities, electric service providers, and community choice aggregators to increase procurement from eligible renewable energy resources to 33 percent of total procurement by 2020 and to 60 percent by 2030. Thus, a portion of the energy consumed during operations would originate from renewable sources. With regard to transportation energy use, the potential homes would comply with all applicable regulations associated with vehicle efficiency and fuel economy. Conclusion Based on the context above, construction and operation of the proposed project would not result in wasteful, inefficient, or unnecessary consumption of energy resources or conflict with or obstruct a State or local plan for renewable energy or energy efficiency. Thus, a less-than-significant impact would occur. Bubb Road Project Initial Study/Mitigated Negative Declaration 38 November 2020 VII. GEOLOGY AND SOILS.

The City of Cupertino, consistent with much of the San Francisco Bay Area, is vulnerable to seismic activity due to the presence of several active faults in the region. However, according to the California Geological Survey Alquist-Priolo Earthquake Fault Zone Maps, the project site is not located within the vicinity of an Alquist-Priolo Earthquake Fault Zone.13 In addition, the project, and any future residential development on the site, would comply with all applicable State and local regulations, including the CBSC. The CBSC provides minimum standards to protect property and public safety by regulating the design and construction of excavations, foundations, building frames, retaining walls, and other building elements to mitigate the effects of seismic shaking and adverse soil conditions. The CBSC contains provisions for earthquake safety based on factors including occupancy type, the types of soil and rock on-site, and the strength of ground shaking with specified 13 California Geological Survey. Earthquake Zones of Required Investigation Cupertino Quadrangle. September 23, 2002. Bubb Road Project Initial Study/Mitigated Negative Declaration 39 November 2020 probability of occurring at a site. Structures built according to the seismic design provisions of the CBSC should be able to: 1) Resist minor earthquakes without damage; 2) Resist moderate earthquakes without structural damage but with some nonstructural damage; and 3) Resist major earthquakes without collapse but with some structural as well as nonstructural damage. Although conformance with the CBSC does not guarantee that substantial structural damage would not occur in the event of a maximum magnitude earthquake, conformance with the CBSC can reasonably be assumed to ensure that the proposed structure would be survivable, allowing occupants to safely evacuate in the event of a major earthquake. Based on the above, the proposed project would not expose people and structures to potential substantial adverse effects involving rupture of a known earthquake fault or strong seismic ground-shaking and a less-than-significant impact would occur. aiii, aiv, c. The proposed project’s potential effects related to liquefaction, landslides, lateral spreading, and subsidence/settlement are discussed in detail below. Liquefaction Liquefaction is a phenomenon in which granular material is transformed from a solid state to a liquefied state as a consequence of increased pore-water pressure and reduced effective stress. Increased pore-water pressure is induced by the tendency of granular materials to densify when subjected to cyclic shear stresses associated with earthquakes. According to the General Plan EIR Figure 4.5-4, the project site is not located in an area with a high liquefaction probability. Furthermore, the CBSC provides standards to protect property and public safety by regulating the design and construction of excavations, foundations, building frames, retaining walls, and other building elements, which would further reduce the potential for seismic-related ground failure, including liquefaction. Compliance with the aforementioned standards would ensure that the potential for risks related to liquefaction would be less than significant. Landslides Seismically-induced landslides are triggered by earthquake ground shaking. The risk of landslide hazard is greatest in areas with steep, unstable slopes. Figure HS-5 in the City’s General Plan identifies areas in the City that are potentially at risk for fault rupture, landslides, and liquefaction/inundation. Areas mapped as Liquefaction/Inundation Zones by the City are also generally at risk for lateral spreading hazards.14 Per Figure HS-5, the 14 City of Cupertino. General Plan: Community Vision 2015 – 2040 [pg. E-5]. October 20, 2015. Bubb Road Project Initial Study/Mitigated Negative Declaration 40 November 2020 site is located within a Valley Zone, which is defined as an area with relatively low levels of geologic hazard risk. Further, the General Plan EIR concludes that compliance with the policies within the General Plan and the Cupertino Municipal Code would reduce any potential impacts related to landslides to a less-than-significant level. Lateral Spreading Lateral spreading is horizontal/lateral ground movement of relatively flat-lying soil deposits towards a free face such as an excavation, channel, or open body of water; typically, lateral spreading is associated with liquefaction of one or more subsurface layers near the bottom of the exposed slope. The project site is located on relatively flat land, and is not located near any open faces that would be considered susceptible to lateral spreading. Therefore, the potential for lateral spreading to pose a risk to the proposed development is relatively low. Further, the General Plan EIR concludes that impacts related to lateral spreading would be reduced to a less- than-significant level with compliance with the policies set forth in the Cupertino General Plan and Municipal Code. Subsidence/Settlement Subsidence is the settlement of soils of very low density generally from either oxidation of organic material, or desiccation and shrinkage, or both, following drainage. Subsidence takes place gradually, usually over a period of several years. Given that the proposed project would comply with the CBSC, the potential for subsidence to pose a risk to the proposed development is relatively low. In addition, the General Plan EIR concludes that impacts related to subsidence/settlement would be reduced to a less-than-significant level with compliance with Municipal Code requirements and all applicable General Plan policies. Conclusion Based on the above, the proposed project would not be subject to substantial risks related to liquefaction, landslides, lateral spreading, and subsidence/settlement. If future residences are constructed on-site, compliance with standard construction regulations included in the CBSC would ensure that the homes would not directly or indirectly cause substantial adverse effects, including the risk of loss, injury, or death involving liquefaction, subsidence, or settlement, and would not be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site subsidence, liquefaction, or collapse. Thus, a less-than-significant impact would occur. b. The proposed project would require excavation and grading of the site, including soil excavation and off-haul associated with on-site soil remediation (see Section VIII for Bubb Road Project Initial Study/Mitigated Negative Declaration 41 November 2020 additional discussion). During such stages of construction, topsoil would be exposed. After grading and prior to overlaying the ground surface with future residences, while topsoil would be exposed, the potential exists for wind and/or water erosion to occur, which could affect the project area and potentially inadvertently transport eroded soils to downstream waterways. However, topsoil exposure would be temporary and would cease once future development of the site with single-family homes occurs. The City’s Municipal Code requires applicants to provide and comply with an Interim Erosion and Sediment Control Plan (Interim Plan). The Interim Plan shall show the location of erosion control measures and erosion control planting shall be shown on the site map/grading plan. The applicant shall provide the following information with respect to conditions existing on the site during land-disturbing or filling activities or stockpiling of soil: 1. A delineation and brief description of the measures to be undertaken to retain sediment on the site, including, but not limited to, the designs and specifications or berms and sediment detention basins, and a schedule for their maintenance and upkeep; 2. A delineation and brief description of the surface runoff and erosion control measures to be implemented, including, but not limited, to types and methods of applying mulches, and designs and specifications for diverters, dikes and drains, and a schedule for their maintenance and upkeep; 3. A delineation and brief description of the vegetative measures to be undertaken, including, but not limited to, seeding methods, and type, location and extent of preexisting and undisturbed vegetation types, and a schedule for maintenance and upkeep. Because the project would comply with the City’s interim erosion control requirements, the project would not result in substantial soil erosion or loss of topsoil. Therefore, a less- than-significant impact would occur. d. Expansive soils increase in volume when they absorb water and have the potential to crack or otherwise compromise the integrity of building foundations. According to the City’s General Plan EIR, the project site is not located in an area of the City known to contain highly expansive soils.15 Furthermore, the proposed project would be subject to applicable CBSC regulations and provisions, as adopted in Chapter 16.04 of the City’s Municipal Code. Therefore, the proposed project would not be located on expansive soil, as defined in Table 18-1B of the Uniform Building Code, and a less-than-significant impact would occur. e. The proposed project would include demolition of the on-site structures and subdivision of the lot. However, up to three single-family residences could be developed on the site in the future. Any future residences would connect to the existing sewer system and would not require the use of a septic tank or other alternative waste water disposal method. Therefore, 15 City of Cupertino.

Bubb Road Project Initial Study/Mitigated Negative Declaration 42 November 2020 no impact would occur related to having soils incapable of adequately supporting the use of septic tanks or alternate wastewater disposal systems. f. Paleontological resources or fossils are the remains of prehistoric plant and animal life. As noted in the General Plan EIR, based on a review of the University of California’s Museum of Paleontology’s fossil locality database conducted for all of Santa Clara County, paleontological resources have not been explicitly identified as being found within the City of Cupertino.16 Nonetheless, previously unknown paleontological resources or unique geologic resources could potentially exist within the project site, and any ground-disturbing activity associated with implementation of the proposed project could have the potential to disturb or destroy such resources. The project would be subject to the City’s standard measures listed in Chapter V, Cultural Resources, of this IS/MND, which, as noted in the General Plan EIR, would ensure that any impacts to paleontological resources and unique geologic features are reduced to less than significant. Therefore, the proposed project would not directly or indirectly destroy a unique paleontological resource or site or unique geologic feature, and a less-than-significant impact would occur. 16 City of Cupertino.

Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?     b. Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gasses?     Discussion a,b. Emissions of greenhouse gases (GHGs) contributing to global climate change are attributable in large part to human activities associated with the industrial/manufacturing, utility, transportation, residential, and agricultural sectors. Therefore, the cumulative global emissions of GHGs contributing to global climate change can be attributed to every nation, region, and city, and virtually every individual on earth. An individual project’s GHG emissions are at a micro-scale level relative to global emissions and effects to global climate change; however, an individual project could result in a cumulatively considerable incremental contribution to a significant cumulative macro-scale impact. As such, impacts related to emissions of GHG are inherently considered cumulative impacts. Implementation of the proposed project would cumulatively contribute to increases of GHG emissions. Estimated GHG emissions attributable to future development would be primarily associated with increases of carbon dioxide (CO2) and, to a lesser extent, other GHG pollutants, such as methane (CH4) and nitrous oxide (N2O) associated with area sources, mobile sources or vehicles, utilities (electricity), water usage, wastewater generation, and the generation of solid waste. The primary source of GHG emissions for the project would be mobile source emissions. The common unit of measurement for GHG is expressed in terms of annual metric tons of CO2 equivalents (MTCO2e/yr). A number of regulations currently exist related to GHG emissions, predominantly Assembly Bill (AB 32), Executive Order S-3-05, and Senate Bill (SB 32). AB 32 sets forth a statewide GHG emissions reduction target of 1990 levels by 2020. Executive Order S-3- 05 sets forth a transitional reduction target of 2000 levels by 2010, the same target as AB 32 of 1990 levels by 2020, and further builds upon the AB 32 target by requiring a reduction to 80 percent below 1990 levels by 2050. SB 32 also builds upon AB 32 and sets forth a transitional reduction target of 40 percent below 1990 levels by 2030. In order to implement the statewide GHG emissions reduction targets, local jurisdictions are encouraged to prepare and adopt area-specific GHG reduction plans and/or thresholds of significance for GHG emissions. A discussion of the City’s Climate Action Plan (CAP), as well as applicable BAAQMD thresholds related to GHG emissions, is provided below. Bubb Road Project Initial Study/Mitigated Negative Declaration 44 November 2020 Climate Action Plan As a means of achieving the statewide GHG emissions reduction goals, the City has adopted a CAP. The targets are consistent with statewide goals. In addition, the CAP includes a number of reduction measures intended to be implemented by the City in order to accomplish the reduction goals. The emissions reduction strategies developed by the City follows the BAAQMD’s CEQA Guidelines and the corresponding criteria for a Qualified Greenhouse Gas Emissions Reduction Program as defined by the BAAQMD. Because the provisions included in the CAP mirror the elements required per Section 15.183.5 of the CEQA Guidelines, the CAP is consistent with existing State regulations related to GHG emissions, as well as BAAQMD thresholds of significance. It should be noted that a quantitative threshold for GHG emissions for individual development projects has not been established by the City or set forth in the CAP. The GHG inventory contained in the City’s CAP was derived based on the land use designations and associated densities defined in the City’s General Plan. Future development of single-family homes on the project site would be consistent with the project site’s existing General Plan land use designation, and would not modify the type of use previously anticipated for the site by the City. It should be noted that the potential future residences would result in a slight increase in development intensity relative to existing site uses; however, associated increases in GHG emissions related to such would not be substantial. A CAP Consistency Checklist prepared for the proposed project and potential future single- family residences has been included as Appendix B to this IS/MND. As noted therein, the project would comply with the majority of measures included in the CAP, including, but not limited to, the incorporation of: • Advanced meter infrastructure (Measure C-E-1); • Pedestrian and bicycle infrastructure improvements (Measure C-T-1); • EV charging infrastructure (Measure C-T-7); • Water-efficient fixtures (Measure C-W-1); • Recycling and organic waste diversion (Measure C-SW-1 and C-SW-2); and • Cool roofing materials (Measure C-G-1); In addition, as noted in the Energy section of this IS/MND, the project and any future development on-site would be required to comply with the City’s reach code standards. Compliance with such standards would ensure that future development is all-electric and, consistent with CAP Measure C-T-7, includes EV charging stations. In addition, the City’s reach code was adopted with the intent to support implementation of the goal sets forth within the City’s CAP. As such, compliance with the reach code standards would be consistent with the measures included in the CAP. As such, the proposed project would not conflict with the City’s CAP and, therefore, would not conflict with the applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs. Bubb Road Project Initial Study/Mitigated Negative Declaration 45 November 2020 BAAQMD Thresholds The proposed project is located within the jurisdictional boundaries of the BAAQMD. The BAAQMD threshold of significance for project-level operational GHG emissions is 1,100 MTCO2e/yr. BAAQMD’s approach to developing a threshold of significance for GHG emissions is to identify the emissions level for which a project would not be expected to substantially conflict with existing California legislation adopted to reduce statewide GHG emissions needed to move towards climate stabilization. If a project would generate GHG emissions above the threshold level, the project would be considered to generate significant GHG emissions and conflict with applicable GHG regulations. The proposed project’s estimated construction and operational GHG emissions were quantified using CalEEMod, using the same assumptions as presented in the Air Quality section of this IS/MND. The proposed project’s required compliance with the current CBSC was assumed in the modeling. In addition, the CO2 intensity factor within the model was adjusted to reflect the PG&E’s anticipated progress towards statewide RPS goals. All CalEEMod results are included as Appendix A to this IS/MND. As discussed in Section III, Air Quality, of this IS/MND, the proposed project would include demolition of the on-site structures and subdivision of the site. However, this IS/MND also analyzes the reasonably foreseeable future construction of up to three single- family homes. GHG emissions associated with the demolition of the on-site structures, as well as future construction and operations of the potential future single-family homes are discussed below. Based on the results of the modeling, the project and the potential future development of up to three single-family homes would result in total construction emissions of approximately 107.04 MTCO2e/yr. While neither the City nor BAAQMD have established GHG emissions thresholds for construction, construction emissions associated with the proposed project would be far below the BAAQMD’s adopted operational threshold of 1,100 MTCO2e/yr. Construction-related GHG emissions are a one-time release and are, therefore, not typically expected to generate a significant contribution to global climate change, as global climate change is inherently a cumulative effect that occurs over a long period of time. Furthermore, construction activity associated with the proposed project would occur over a short duration and be limited in scope. The project’s estimated operational emissions are summarized in Table 4 below. As shown in the table, operations of the future single-family residences would result in operational GHG emissions well below the 1,100 MTCO2e/yr threshold. Therefore, the proposed project would not result in operational impacts related to GHG emissions. Bubb Road Project Initial Study/Mitigated Negative Declaration 46 November 2020 Table 4 Project Operational GHG Emissions Emission Source Annual GHG Emissions (MTCO2e/yr) Area 0.54 Energy 11.29 Mobile 28.26 Solid Waste 1.90 Water 0.54 TOTAL ANNUAL GHG EMISSIONS 42.54 Source: CalEEMod, April 2018. Conclusion Based on the above, the proposed project would be consistent with the City’s adopted CAP. In addition, the estimated annual operational and construction GHG emissions would be below the applicable BAAQMD thresholds of significance. As such, the proposed project would not be considered to generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment, or conflict with any applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs. Therefore, impacts would be considered less than significant. Bubb Road Project Initial Study/Mitigated Negative Declaration 47 November 2020 IX. HAZARDS AND HAZARDOUS MATERIALS.

Residential land uses are not typically associated with the routine transport, use, disposal, or generation of substantial amounts of hazardous materials. Future residents on the project site may use common household cleaning products, fertilizers, and herbicides on-site, any of which could contain potentially hazardous chemicals; however, such products would be expected to be used in accordance with label instructions. Due to the regulations governing use of such products and the amount that would be used on the site, routine use of such products would not represent a substantial risk to public health or the environment. Therefore, the project would not create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials, and a less-than- significant impact would occur. b. The following discussion includes an analysis of hazardous and toxic materials that could be used on the project site during construction activities, as well as existing hazardous materials known to be present on the site. Bubb Road Project Initial Study/Mitigated Negative Declaration 48 November 2020 Construction Equipment Construction and demolition activities associated with the proposed project would involve the use of heavy equipment, which would contain fuels and oils, and various other products such as concrete, paints, and adhesives. Small quantities of potentially toxic substances (e.g., petroleum and other chemicals used to operate and maintain construction equipment) would be used at the project site and transported to and from the site during construction. However, the project contractor would be required to comply with all California Health and Safety Codes and local City and County ordinances regulating the handling, storage, and transportation of hazardous and toxic materials. Compliance with such regulations would ensure that the proposed project would not create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment during construction activities, particularly associated with construction equipment. Existing Soil Contamination A Phase I ESA was prepared for the proposed project by Enviro Assessment, PC in November 2017 (see Appendix C).17 The Phase I ESA did not reveal evidence of Recognized Environmental Conditions (RECs), Historical RECs (HRECs), or Controlled RECs (CRECs) in connection with the project site, with the exception of the presence of pesticides and metals above screening levels in the on-site soils due to the property’s historical use as orchard land and use of organochlorine pesticides (OCPs) for pest control. An update to the original Phase II ESA, which was prepared in August 2014, was prepared by Enviro Assessment, PC in November 2017 to address and compare laboratory results from the original Phase II ESA and to update any site characterization recommendations (see Appendix D).18 Due to the elapsed time since the Phase I and Phase II ESA were prepared, Enviro Assessment, PC prepared an Update Memo confirming that the results of the Phase I and Phase II ESA remain applicable and valid.19 As noted therein, there have not been any changes in use or new concerns at the project site, and the conclusions and recommendations from the previous ESAs remain relevant. As part of the Phase II ESA, and in accordance with Department of Toxic Substances Control (DTSC) guidelines for sampling for agricultural chemicals, 16 discrete soil samples were collected across the entirety of the project site, including the crawlspace of the residence, under concrete, and within two feet of existing structures. The soil samples were analyzed for OCPs (including, but not limited to, chlordane, DDT, dieldrin, and heptachlor) and metals. Concentrations were compared to the applicable Environmental Screening Levels (ESLs), which are the concentrations of contaminants in soils and groundwater established by the Regional Water Quality Control Board (RWQCB) used to determine the relative risks to human health and the environment. Generally, the presence 17 Enviro Assessment, PC. Phase I Environmental Site Assessment, Bubb Road Property, 11226 Bubb Road, Cupertino, CA 95014. November 17, 2017. 18 Enviro Assessment, PC.

Bubb Road Project Initial Study/Mitigated Negative Declaration 49 November 2020 of a chemical in soil or groundwater at concentrations below the corresponding ESL can be assumed to not pose a significant threat to human health or the environment. Chlordane and dieldrin were the only OCPs detected above their respective ESLs. Concentrations of chlordane were detected in 11 of the 16 samples, with eight of the samples showing concentrations above the ESL. Concentrations of dieldrin were detected in only two of the 16 samples, with only one of the samples showing concentrations above the ESL. Metals detected in concentrations exceeding the relative ESLs included arsenic, cobalt, and lead. Arsenic was detected in all 16 samples at levels exceeding the ESL. Cobalt was detected in all 16 samples, but only two samples were above the ESL. Lead was detected in all 16 samples, but only one sample was above the ESL. Although arsenic was detected in all samples at concentrations exceeding the ESL, the concentrations are within the range of naturally-occurring background concentrations typical for California soils, with the exception of one sample. Based on the above, construction workers and/or future occupants could be exposed to existing soil contaminants. Therefore, the proposed project could create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment, particularly related to existing soil contamination at the site. Asbestos-Containing Materials and Lead-Based Paint Asbestos is the name for a group of naturally occurring silicate minerals that are considered to be “fibrous” and, through processing, can be separated into smaller and smaller fibers. The fibers are strong, durable, chemical resistant, and resistant to heat and fire. They are also long, thin, and flexible, such that they can be woven into cloth. Because of the above qualities, asbestos was considered an ideal product and has been used in thousands of consumer, industrial, maritime, automotive, scientific, and building products. However, later discoveries found that, when inhaled, the material caused serious illness. For buildings constructed prior to 1980, the Code of Federal Regulations (29 CFR 1926.1101) states that all thermal system insulation (boiler insulation, pipe lagging, and related materials) and surface materials must be designated as “presumed asbestos- containing material” unless proven otherwise through sampling in accordance with the standards of the Asbestos Hazard Emergency Response Act. Because the existing residence was built prior to 1980, the potential exists that asbestos-containing materials were used in the construction of the on-site residence. Lead-based paint (LBP) is defined by federal guidelines as any paint, varnish, stain, or other applied coating that has one milligram of lead per square centimeter or greater. Lead is a highly toxic material that may cause a range of serious illnesses, and in some cases death. In buildings constructed after 1978, the presence of LBP is unlikely. Structures built prior to 1978, and especially prior to the 1960s, are expected to contain LBP. As previously mentioned, the existing residence on the property was constructed in 1955. Therefore, the potential exists that LBPs are present in the on-site residence. Bubb Road Project Initial Study/Mitigated Negative Declaration 50 November 2020 Based on the age of the existing on-site residence, asbestos-containing materials and LBP are presumed to be present. Thus, without implementation of the appropriate safety measures, the proposed project could potentially expose construction workers during demolition activities to LBP and asbestos-containing materials. The City of Cupertino Building Division requires asbestos and LBP testing as a standard condition of approval. Compliance with the City’s standard conditions of approval would ensure that appropriate safety measures associated with asbestos and LBP are implemented, and demolition of the on-site structures would not expose construction workers to hazardous materials, such as LBP or asbestos-containing materials. Conclusion Based on the above, development of the proposed project could create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment, particularly associated with contaminated soils. Therefore, a potentially significant impact would occur. Mitigation Measure(s) Implementation of the following mitigation measure would reduce the above impact to a less-than-significant level. VIII-1.Prior to issuance of any grading permits, the following measures shall be reflected on the project grading and foundation plans, subject to review and approval by the Santa Clara County Environmental Health Department: •Soil adjacent (within three feet) to the foundation along the front of the house shall be removed to a depth of one foot and off-hauled by a licensed hazardous waste contractor (Class A) and contractor personnel that have completed 40-hour OSHA hazardous training. The soil shall be disposed of appropriately in accordance with applicable federal, State, and local regulations associated with hazardous waste. •After demolition of the existing residence, the soil within the foundation shall be removed to a depth of one foot and off-hauled by a licensed hazardous waste contractor (Class A) and contractor personnel that have completed 40-hour OSHA hazardous training. The soil shall be disposed of appropriately in accordance with applicable federal, State, and local regulations associated with hazardous waste. The project applicant shall provide proof of implementation of the above measures to the Planning Department and the Santa Clara County Environmental Health Department. Bubb Road Project Initial Study/Mitigated Negative Declaration 51 November 2020 c. Regnart Elementary School is located within one-quarter mile southeast of the project site. As discussed above, potential future development and operation of the project site with residential uses would not include any activities that would involve the routine transport, use, disposal, or generation of substantial amounts of hazardous materials. As such, future operations on the project site would not emit any hazardous emissions, substances, or waste. However, as discussed above, based on the age of the existing on-site residence, the potential exists to encounter asbestos-containing materials and LBP. If the on-site structures are found to contain asbestos-containing materials and LBP, the standard conditions of approval required by the City of Cupertino’s Building Division would require the construction contractor to handle and dispose of the potentially hazardous materials in accordance with all applicable federal, State, and local regulations, which would ensure that construction workers and the surrounding community, including the nearby school, would not be exposed to asbestos-containing materials and LBPs during demolition activities. As also discussed above, the potential exists to encounter contaminated soil during construction and ground-disturbing activities. Mitigation Measure VIII-1 would ensure that all contaminated soil on the site would be properly removed, handled, and disposed, which would ensure that any effects associated with an accidental release of materials would be minimized and remediated appropriately. Furthermore, dust control methods such as watering exposed soils, covering them during and after excavation, and air monitoring around the perimeter of the affected location are standard procedures that would likely be used. Other methods that could be used to reduce exposure of the surrounding community, including students at the nearby school, to potential hazards associated with contaminated soil removal activities could include placing impervious covers over the soils and backfilling the excavated soil with clean fill. In addition, worker and public health and safety requirements mandated by State laws and regulations would apply during contaminated soil removal activities, thereby minimizing the potential for the above- mentioned exposures to occur. As a result, the proposed project would not emit hazardous emissions, substances, or waste within one-quarter mile of an existing or proposed school, and a less-than-significant impact would occur. d. The proposed project would not be located on a site that is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5.20 Therefore, the project would not create a significant hazard to the public or the environment related to such, and no impact would occur. e. The nearest airport to the project site is the San Jose International Airport, located approximately 7.5 miles northeast of the site. As such, the project site is not located within two miles of any public airports and does not fall within an airport land use plan area. Therefore, no impact related to a safety hazard for people residing or working in the project area would occur related to such. 20 California Department of Toxic Substances Control.

The City of Cupertino Office of Emergency Services is responsible for coordinating agency response to disasters or other large‐scale emergencies in the City of Cupertino, with assistance from the Santa Clara County Office of Emergency Services and the Santa Clara County Fire Department (SCCFD). The Cupertino Emergency Operations Plan establishes policy direction for emergency planning, mitigation, response, and recovery activities within the City.21 Implementation of the proposed project would include widening of Krzich Place along the project frontage; however, such modifications would not physically interfere with the Emergency Operations Plan, particularly with identified emergency routes. Furthermore, the proposed project would not include land uses or operations that could impair implementation of the plan. Therefore, the proposed project would not interfere with an emergency evacuation or response plan, and a less-than-significant impact would occur. g. According to the California Department of Forestry and Fire Protection (CAL FIRE) Fire and Resource Assessment Program, the project site is not located within a Very High Fire Hazard Severity Zone.22 In addition, the site is currently developed, surrounded by existing development, and is not located adjacent to wildlands. Therefore, the proposed project would not expose people or structures to the risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands, and a less-than-significant impact would occur. 21 City of Cupertino.

The following section describes the project’s consistency with applicable water quality standards and waste discharge requirements during construction and operation. Construction The project site is currently developed with a residential use. As such, the site contains a substantial amount of impervious areas. Nonetheless, during the early stages of future construction activities, topsoil would be exposed due to grading of the site. After grading and prior to overlaying the ground surface with impervious surfaces and structures, the potential exists for wind and water erosion to discharge sediment and/or urban pollutants into stormwater runoff, which could adversely affect water quality downstream. The State Water Resources Control Board (SWRCB) regulates stormwater discharges associated with construction activities where clearing, grading, or excavation results in a land disturbance of one or more acres. The project site is 32,316 square feet (0.74-acre) and, thus, construction activities would not be regulated by the SWRCB. However, the City’s Municipal Code requires applicants to provide and comply with an Interim Erosion Bubb Road Project Initial Study/Mitigated Negative Declaration 54 November 2020 and Sediment Control Plan (Interim Plan). The Interim Plan shall show the location of erosion control measures and erosion control planting shall be shown on the site map/grading plan. The applicant shall provide the following information with respect to conditions existing on the site during land-disturbing or filling activities or stockpiling of soil: 1. A delineation and brief description of the measures to be undertaken to retain sediment on the site, including, but not limited to, the designs and specifications or berms and sediment detention basins, and a schedule for their maintenance and upkeep; 2. A delineation and brief description of the surface runoff and erosion control measures to be implemented, including, but not limited, to types and methods of applying mulches, and designs and specifications for diverters, dikes and drains, and a schedule for their maintenance and upkeep; 3. A delineation and brief description of the vegetative measures to be undertaken, including, but not limited to, seeding methods, and type, location and extent of preexisting and undisturbed vegetation types, and a schedule for maintenance and upkeep. Because the project would comply with the City’s interim erosion control requirements, the project would not violate any water quality standards or waste discharge requirements, or otherwise degrade water quality, during construction. Operation The potential future residential use of the project site would not involve operations typically associated with the generation or discharge of polluted water. Thus, typical operations on the project site would not violate any water quality standards or waste discharge requirements, nor degrade water quality. However, the potential for urban runoff would be increased with the addition of impervious surfaces on the site, which could contain pollutants if the runoff comes into contact with vehicle fluids on parking surfaces and/or landscape fertilizers and herbicides prior to reaching downstream waters. The City of Cupertino has adopted the County C.3 Stormwater Standards, which require new development and redevelopment projects that create or alter 10,000 sf or more of impervious area to contain and treat all stormwater runoff from the project site. The proposed project would create and/or replace a total of 15,007 sf of impervious surfaces. Thus, the project would be subject to the requirements of the C.3 Stormwater Standards related to stormwater treatment, which are included in the City’s NPDES General Permit. The C.3 Stormwater Standards require incorporation of site design measures, source control measures, stormwater treatment measures, and hydromodification management measures, if applicable. A preliminary Stormwater Control Plan has been prepared for the proposed project (see Figure 5). As shown in the Stormwater Control Plan, the proposed project would involve four drainage management areas (DMAs), including one on each proposed lot and one Bubb Road Project Initial Study/Mitigated Negative Declaration 55 November 2020 associated with the roadway dedication area. Runoff from the DMA on each lot would be directed towards an associated bioretention basin. Per the C.3 Stormwater Handbook, DMA 4, which consists of the roadway dedication, would be exempt from the C.3 Standards. The bioretention basins and pervious areas (i.e., landscaped areas) would treat stormwater primarily by filtering runoff slowly through an active layer of soil, naturally allowing for removal of pollutants. Runoff from future rooftops would be directed towards the on-site landscaped areas and grassy swales to maximize infiltration and minimize pollutants before draining to the bioretention basins. It should be noted that per Section 9.18.210 of the Municipal Code, the City prohibits the use of copper metal roofing and copper architectural materials. Per the Stormwater Control Plan prepared for the proposed project, each of the bioretention basins would be sized to exceed the minimum volume requirement necessary to adequately handle all runoff from the proposed impervious surfaces and landscaping within each DMA. Thus, the proposed project would comply with the requirements of the SWRCB and the RWQCB, and would meet or exceed C.3 Standards related to stormwater treatment. During operation, the project would comply with all relevant water quality standards and waste discharge requirements, and would not degrade water quality. Conclusion Based on the above, the project would comply with all applicable water quality and waste discharge regulations during construction and operation, and would not involve uses associated with the generation or discharge of polluted water. Therefore, a less-than- significant impact would occur related to a violation of water quality standards or waste discharge requirements or degradation of water quality. b,e. Water supplied to the City of Cupertino is provided by the Santa Clara Valley Water District through groundwater, local surface water, imported surface water from the State Water Project and Central Valley Project, recycled and purified water, and transfers.23 As discussed previously, the project site is currently developed with an existing single- family residence. Potential future residential development on the site would not substantially increase demand for water supplies associated with the site, including groundwater, and the proposed on-site drainage system would allow for stormwater to percolate into the underlying soils, contributing to the recharge of groundwater. Future residential development on-site would not substantially deplete groundwater supplies or interfere substantially with groundwater recharge. Given that potential future buildout of the site with single-family residences would be consistent with the site’s current General Plan land use and zoning designations, such development would not result in increased use of groundwater supplies beyond what has been anticipated for the site by the City and accounted for in the Santa Clara Valley Water 23 Santa Clara Valley Water District. Urban Water Management Plan. 2015. Bubb Road Project Initial Study/Mitigated Negative Declaration 56 November 2020 District’s 2015 Urban Water Management Plan (UWMP). Per the UWMP, water supplies and reserves are projected to meet expected demand for normal-year and single dry-year scenarios through 2035. The Santa Clara Valley Water District anticipates facing water shortage in multiple dry-year scenarios. However, a Water Shortage Contingency Plan is in place, and a potential water supply shortage would not be a result of the proposed project.24 Therefore, the proposed project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the Santa Clara Valley Groundwater Basin and Gilroy-Hollister Valley Groundwater Basin. In addition, the project would not conflict with or obstruct implementation of a water quality control plan, including the 2015 UWMP and the Santa Clara Valley Water District Groundwater Management Plan. Thus, a less-than- significant impact would occur. c.i-iii. The project site is currently developed with an existing residence and other impervious surfaces such as a driveway, patio, porch and shed. As such, potential future development of the site with single-family residences would result in a substantial increase in impervious surfaces or runoff from what currently exists on-site. In addition, as discussed above, the project would include a drainage system that would manage all on-site runoff without directly connecting to the City’s existing stormwater drainage system. Runoff entering the perforated drainage pipes and the bubbler drain system would be able to infiltrate the soil and erosion, siltation, and/or flooding would not occur. In conclusion, the proposed project would not substantially alter the existing drainage pattern of the site or area in a manner which would result in erosion, siltation, or flooding on- or off-site, or create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. Consequently, the proposed project would result in a less-than- significant impact related to such. c.iv. According to the City’s General Plan,25 as well as the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) Number 06085C0209H,26 the project site is located in Zone X, which is an area of minimal flood hazard, outside of the 100-year floodplain. The site is not classified as a Special Flood Hazard Area or otherwise located within a 100-year or 500-year floodplain. Therefore, development of the proposed project would not impede or redirect flood flows and no impact would result. d. As discussed under question ‘c.iv’ above, the project site is not located within a flood hazard zone. Thus, the proposed project would not be subject to substantial flooding risks. Tsunamis are defined as sea waves created by undersea fault movement, whereas a seiche is a long-wavelength, large-scale wave action set up in a closed body of water such as a 24 Santa Clara Valley Water District.

Bubb Road Project Initial Study/Mitigated Negative Declaration 57 November 2020 lake or reservoir. Tsunamis typically affect coastlines and areas up to one-quarter mile inland. The project area is located over 20 miles from the Pacific Ocean. Due to the project’s distance from the coast, the project site would not be exposed to flooding risks associated with tsunamis. Seiches do not pose a risk to the proposed project, as the project site is not located in close proximity to any large closed bodies of water. Therefore, the proposed project would not pose a risk related to the release of pollutants due to project inundation due to flooding, tsunami, or seiche, and no impact would occur.

Would the project: Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less-Than- Significant Impact No Impact a. Physically divide an established community?     b. Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?     Discussion a. A project risks dividing an established community if the project would introduce infrastructure or alter land use so as to change the land use conditions in the surrounding community, or isolate an existing land use. The project site currently contains a single- family residence. Given that the proposed project would allow for future redevelopment of the site with three new single-family residences, the proposed project would not alter the land use of the site. Accordingly, the proposed project would not change the land use conditions in the area or isolate an existing land use. In addition, the project would be consistent with the site’s existing zoning and General Plan land use designations. As such, the proposed project would not physically divide an established community and a less- than-significant impact would occur. b. The City of Cupertino General Plan designates the site as Low Density (1-5 DU/Ac.), and the site is currently zoned Single-Family Residential (R1-7.5). The proposed project would include division of the site into two 9,746 square-foot lots and one 11,915 square-foot lot, with the dedication of approximately 943 square-feet of land to the City to allow for the widening of the Krzich Place right-of-way along the project frontage. The three new lots would maintain the existing zoning and General Plan land use designations for the site, and would be consistent with Sections 19.28.050 and 19.28.060 of the City’s Municipal Code relating to zoning districts and site development regulations. As discussed throughout this IS/MND, the proposed project would not result in any significant environmental effects that cannot be mitigated to a less-than-significant level by the mitigation measures provided herein. In addition, the proposed project would not conflict with City policies or regulations adopted for the purpose of avoiding or mitigating an environmental effect. For example, the proposed project would comply with all relevant City policies and guidelines, including, but not limited to, the standards set forth in Chapter 10.48, Community Noise Control, and Chapter 9.18, Stormwater Pollution Prevention and Watershed Protection, of the City’s Municipal Code. Based on the above, the project would not conflict with any applicable land use plans, policies, or regulations adopted for the purpose of avoiding or mitigating an environmental effect, and a less-than-significant impact would occur.

The project site is located in a developed area and is currently developed with residential use. According to the City’s General Plan, the project site is located in an area which is unsuitable for mineral extraction.27 The proposed project would include subdivision of the project site, with the intention of future redevelopment of the site with three new single- family residences. Therefore, no impact to mineral resources would occur as a result of the proposed project. 27 City of Cupertino. General Plan: Community Vision 2015 – 2040 [pg. ES-10]. Adopted October 20, 2015. Bubb Road Project Initial Study/Mitigated Negative Declaration 60 November 2020 XIII. NOISE. Would the project result in: Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less-Than- Significant Impact No Impact a. Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?     b. Generation of excessive groundborne vibration or groundborne noise levels?     c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?     Discussion a. The existing noise environment of the site is currently defined by traffic noise on Krzich Place and Bubb Road. Such traffic is primarily generated by the surrounding residences in the project vicinity, as well as the occupied single-family residence currently located on the project site. The proposed project would include demolition of the existing on-site structures and subdivision of the project site, which may lead to potential future redevelopment of the site with up to three single-family residences. The project could be considered to result in a potentially significant impact if the net increase in traffic generated by the proposed project would cause an exceedance of noise levels established in the City’s Municipal Code or an increase in the ambient noise levels in the project vicinity. Construction Noise During demolition of the existing on-site structures and widening of the Krzich Place right- of-way, as well as during potential future construction of residences on the site, noise from such activities would temporarily add to the noise environment in the project vicinity. Noise would also be generated during the construction phase by truck traffic associated with transport of heavy materials and equipment to and from the project site. However, per Section 10.48.053 of the City’s Municipal Code, grading, construction, and demolition activities are permitted to exceed the City’s established noise limits during daytime hours provided that any piece of equipment involved in such activities has high-quality noise mufflers and abatement devices installed, is in good condition, and the activities meet certain established criteria. Compliance with the Municipal Code requirements would be verified as part of the City’s standard conditions of approval. Furthermore, noise associated with construction activities would be temporary, would occur intermittently throughout development of the project site, and would occur on a relatively small scale. Thus, while demolition and construction activities associated with the project could result in temporary increases in noise levels at nearby noise-sensitive Bubb Road Project Initial Study/Mitigated Negative Declaration 61 November 2020 receptors, such increases would not be substantial, would be minimized through compliance with the City’s Municipal Code, and would be typical of residential construction activities. Operational Noise Residences are not typically associated with the generation of substantial noise. In addition, future development of the site would involve an increase of only two residences compared to existing conditions, which would not be considered a substantial increase in potential noise sources. Thus, future development on the project site would not result in a significant increase in ambient noise levels. As discussed in the Transportation and Circulation section of this IS/MND, operations associated with future single-family residences on the project site would be anticipated to generate a total of 29 ADT. A total of 29 new vehicle trips spread over a 24-hour period would not result in a substantial permanent increase in ambient noise levels in the project vicinity above existing noise levels. Furthermore, approximately one third of the trips that would be generated by future residents would replace trips currently generated by the occupied single-family residence on the project site. Therefore, given that the proposed project, or future redevelopment of the site with residential uses, would not substantially increase the number of vehicle trips associated with the project site, the project and future development of residential uses on the site would not result in the exposure of persons to or generation of noise levels in excess of standards established in City of Cupertino Municipal Code, or substantially increase ambient noise levels in the project vicinity above levels existing without the project. Conclusion Based on the above, construction and operation of the proposed project would not result in the generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the City’s General Plan and the Municipal Code. Thus, a less-than-significant impact would occur. b. Heavy-duty construction equipment would be used during demolition of the on-site structures and future potential construction of single-family residences on the site (e.g., tractors, pavers, bulldozers). Such equipment has the potential to generate groundborne vibration. Levels of vibration include imperceptible vibrations at low levels, low rumbling and minor vibration at moderate levels, and structural or architectural damage at high levels. For structural damage, the California Department of Transportation (Caltrans) uses a vibration limit of 0.5 inches per second, peak particle velocity (in/sec, PPV) for buildings structurally sound and designed to modern engineering standards, and 0.2 in/sec PPV for buildings that are found to be structurally sound but where structural damage is a major concern. The threshold of 0.2 in/sec PPV is also used by Caltrans as the threshold for human annoyance caused by vibration. Although all surrounding structures are assumed to be structurally sound, the 0.2 in/sec PPV threshold offers a conservative value with regard Bubb Road Project Initial Study/Mitigated Negative Declaration 62 November 2020 to structural damage and is used as the threshold of significance for the analysis within this IS/MND. The primary vibration-generating activities associated with the project would occur during demolition of the existing on-site structures, construction of up to three single-family residences, and widening of the Krzich Place right-of-way. Table 5 below presents typical vibration levels that could be expected from construction equipment at a distance of 25 feet. Table 5 Vibration Source Levels for Construction Equipment Equipment PPV at 25 ft (in/sec) Large Bulldozer 0.089 Caisson drilling 0.089 Loaded trucks 0.076 Jackhammer 0.035 Small bulldozer 0.003 Source: Caltrans, Transportation and Construction Vibration Guidance Manual, September 2013. The most significant source of ground-borne vibrations during construction would be the use of large bulldozers, which, as shown above, would generate vibrations of approximately 0.089 in/sec PPV at a distance of 25 feet.28 The nearest buildings relative to the project site are the existing single-family residences located to the north, east, and west of the site. The nearest residence is situated approximately 12 feet at the closest point from the nearest proposed construction areas. Using the maximum vibration level anticipated during construction of 0.089 in/sec PPV at 25 feet and adjusting for a distance of 12 feet,29 the maximum vibration levels anticipated at the nearest residence would be approximately 0.19 in/sec PPV during construction activities associated with the project, which would be below the applicable 0.2 in/sec PPV threshold. In addition, only portions of the site would be disturbed at a time, with operation of construction equipment occurring intermittently throughout the course of a day. Thus, construction equipment on-site would not operate at a distance of 12 feet to the nearest residence continuously throughout the entire construction period or for an extended amount of time. As such, groundborne vibrations associated with development on the project site would not damage any existing buildings. Additionally, construction activities would be temporary in nature and would be limited to normal daytime working hours in accordance with Section 10.48.053 of the City’s Municipal Code. Therefore, a less-than-significant impact would occur related to exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels. c. The project site is located approximately 7.5 miles southwest of the nearest airport, which is the San Jose International Airport. Given the distance between the airport and the project site, noise levels resulting from aircraft traffic at the nearest airport would be negligible at the project site. Therefore, a less-than-significant impact would occur. 28 California Department of Transportation. Transportation and Construction Vibration, Guidance Manual.

Would the project: Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less-Than- Significant Impact No Impact a. Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (e.g., through projects in an undeveloped area or extension of major infrastructure)?     b. Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?     Discussion a. The proposed project would involve subdivision of the project site and allow for future development of three new single-family homes. The increase of two homes from existing conditions would not result in a substantial increase in population and, thus, the project would not be considered to induce substantial population growth through the construction of new homes. In addition, the project would be consistent with the existing zoning and General Plan land use designations for the site. Therefore, population growth associated with buildout of the site would not be considered unplanned population growth and was previously anticipated for buildout of the site under the General Plan. Consequently, a less- than-significant impact would occur with regard to the project inducing substantial population growth. b. The project site currently contains a single-family residence. The existing on-site structure would be demolished as part of the project. The proposed subdivision of the site would allow for future redevelopment of the site with up to three new single-family residences. The demolition of one single-family residence would not result in displacement of a substantial number of housing or people and would not necessitate the construction of replacement housing elsewhere. In addition, given that future redevelopment of the site with up to three single-family residences could occur, the future residences would provide housing sufficient to replace the existing residence. . Therefore, a less-than-significant impact would occur. Bubb Road Project Initial Study/Mitigated Negative Declaration 64 November 2020 XV. PUBLIC SERVICES. Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less- Than-Significant Impact No Impact a. Fire protection?     b. Police protection?     c. Schools?     d. Parks?     e. Other Public Facilities?     Discussion a. Fire protection services to the project area are provided by the Santa Clara County Fire Department (SCCFD), which serves Santa Clara County and the communities of Campbell, Cupertino, Los Altos, Los Altos Hills, Los Gatos, Monte Sereno, and Saratoga. The SCCFD operates 17 fire stations; the Seven Springs Fire Station, located at 21000 Seven Springs Parkway, currently serves the project site. The SCCFD would continue to provide service following construction activities associated with the proposed project. Given that the proposed project and potential future development of the site with up to three single- family residences would be consistent with the existing land uses on the site and the General Plan land use designation for the site, provision of fire protection services to the project site has been previously anticipated by the City. In addition, demand for fire protection services would not substantially increase, as the site is currently developed with a residential use. Per Section 16.40.060 of the City’s Municipal Code, the proposed project would be required to pay applicable fire protection fees to the SCCFD. In addition, any future residential buildings would be constructed in accordance with the fire protection requirements of the 2019 California Fire Code, which contain provisions to minimize fire hazard risks. Therefore, the proposed project would have a less-than-significant impact related to the need for new or physically altered fire protection facilities, the construction of which could cause significant environmental impacts. b. The City of Cupertino contracts with the Santa Clara County Sheriff’s Office (Sheriff’s Office) and the West Valley Patrol Division for police protection services. The West Valley Patrol Division is headquartered at the Westside Sheriff’s Substation at 1601 South De Anza Boulevard in Cupertino. Given that the project site is already developed with a residential use and provided with police protection services, and the project and possible future development would be consistent with the City’s General Plan land use designation, the project would not substantially increase the demand for police protection services at the site from what currently occurs or what has been anticipated by the City for the site. Therefore, the proposed project would have a less-than-significant impact related to the Bubb Road Project Initial Study/Mitigated Negative Declaration 65 November 2020 need for new or physically altered police protection facilities, the construction of which could cause significant environmental impacts. c. Public schools in the City of Cupertino are managed by the Cupertino Union School District (CUSD) and the Fremont Union High School District (FUHSD). The proposed project would be required to pay the school impact fees specified in the City’s General Plan.30 As noted in the General Plan, in accordance with Senate Bill 50, school impact mitigation fees are presumed to fully mitigate any school impacts associated with development. Because the project applicant would be required to pay the applicable school impact fees, the proposed project would result in a less-than-significant impact regarding an increase in demand for schools. d,e. The City of Cupertino assesses park maintenance fees for new residential development based on the density of the proposed development. Given that the proposed project could allow for future construction of up to three single-family residences on the project site, any future development would be required to comply with all applicable provisions set forth within Chapter 13.08, Park Land Dedication Fee, Chapter 14.05, Park Maintenance Fee, and Chapter 18.16, Subdivision Maps, of the City’s Municipal Code, including payment of fees. The final amount of applicable fees would be determined by the Director of Public Works and would help fund improvements to and expansion of park facilities within the City. Therefore, the proposed project would have a less-than-significant impact related to the need for new or physically altered parks or other public facilities, the construction of which could cause significant environmental impacts. 30 City of Cupertino.

Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment?     Discussion a,b. The proposed project would include the subdivision of the project site into three single- family lots. The subdivision would allow for future construction of up to three new single- family homes. Residents of the future development would likely use existing neighborhood, regional, parks and/or other recreational facilities. However, given that the project site is currently developed with a residential use, the proposed project would not be anticipated to substantially increase the demand for parks or other recreational facilities associated with the site. In addition, development of the site with residential uses has been previously anticipated in the City’s General Plan. As discussed in Section XIV, Public Services, above, the project applicant would be required to comply with to the requirements set forth within Chapter 13.08, Park Land Dedication Fee, Chapter 14.05, Park Maintenance Fee, and Chapter 18.16, Subdivision Maps, of the City’s Municipal Code, including payment of applicable fees. Therefore, the proposed project would not be expected to result in substantial physical deterioration of any existing neighborhood or regional parks or other recreational facilities, and would not require the construction or expansion of facilities which might have an adverse physical effect on the environment. Thus, a less-than-significant impact would occur. Bubb Road Project Initial Study/Mitigated Negative Declaration 67 November 2020 XVII. TRANSPORTATION AND CIRCULATION.

As noted throughout this IS/MND, the proposed subdivision would allow for the potential future construction of up to three new single-family homes. While development plans for on-site homes do not exist at this time, this IS/MND analyzes environmental impacts associated with the possible future development of up to three residences to provide a worst-case analysis. The Institute of Traffic Engineer’s (ITE) Trip Generation Handbook was used to estimate weekday AM, PM, and daily trip generation forecasts for the potential future redevelopment of the site with up to three residences.31 As shown in Table 6 below, the future residences would be expected to result in a total of 29 average daily trips (ADT), with two trips occurring during the AM peak hour and three trips occurring during the PM peak hour. Considering the existing on-site home generates daily vehicles trips as well, redevelopment of the site with three residences would result in a net change of 19 additional ADT, with one additional trip during the AM peak hour and two additional trips during the PM peak hour. Table 6 Weekday Project Trip Generation Rates and Estimates Scenario Units Rate Daily Trips AM Peak Hour PM Peak Hour Rate Total Rate Total Existing Land Use 1 9.52 10 0.75 1 1.00 1 Proposed Project 3 9.52 29 0.75 2 1.00 3 Net Change +2 -- +19 -- +1 -- +2 Note: Rounding may result in minor discrepancies between trip generation rate and number of trips.

Bubb Road Project Initial Study/Mitigated Negative Declaration 68 November 2020 than 100 peak hour trips, preparation of a traffic impact study for the proposed project and potential homes is not required and the project is not subject to review by the VTA. Because the project and future single-family residences would result in less than 100 peak hour trips, and traffic associated with buildout of the site has been previously analyzed in the General Plan EIR, the project would not be expected to adversely impact nearby intersections or roadways. In addition, the project applicant would be required to pay applicable transportation impact fees, which are intended to fund roadway infrastructure improvements and mitigate traffic impacts from development projects. Therefore, the proposed project would not conflict with an applicable program, plan, ordinance, or policy addressing the roadway system. Bike lanes and sidewalks are present on Bubb Road, and bicycle travel in the project vicinity remains a viable transportation option. In addition, the project would include the installation of protected bicycle lanes along McClellan Road, which would further encourage the use of alternative transportation. Sidewalks would be installed along the project frontages, including a new detached sidewalk along Bubb Road, as part of the project. The nearest transit stop relative to the project site is located at the intersection of Stelling Road and McClellan Road, approximately 1.2 miles northeast of the project site. Thus, residents of any future single-family homes on the site would be provided with reasonable access to the City’s public transportation system. The City of Cupertino has adopted the 2018 Pedestrian Transportation Plan and the 2016 Bicycle Transportation Plan.33,34 The plans set forth standards for future development of pedestrian and bicycle infrastructure, and include descriptions of planned street improvements. Per Figure 3-7, Bikeway Projects, of the 2016 Bicycle Transportation Plan, Class II bike lanes currently exist along Bubb Road, and the project would not interfere with any planned improvements. Figure 45, Priority Projects, of the 2018 Pedestrian Transportation Plan depicts high priority pedestrian infrastructure improvements. A planned sidewalk segment is located near the project site, along Bubb Road and north of Krzich Place. Considering the project would include installation of a new detached sidewalk along Bubb Road, the project would contribute towards implementation of the infrastructure improvements planned within the 2018 Pedestrian Transportation Plan. Based on the above, a less-than-significant impact would occur related to conflicting with a program, plan, ordinance, or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities. b. Section 15064.3 of the CEQA Guidelines provides specific considerations for evaluating a project’s transportation impacts. Pursuant to Section 15064.3 of the CEQA Guidelines, analysis of VMT attributable to a project is the most appropriate measure of transportation impacts. Other relevant considerations may include the effects of the project on transit and non-motorized travel. 33 City of Cupertino. Pedestrian Transportation Plan. February 2018. 34 City of Cupertino. 2016 Bicycle Transportation Plan. June 2016. Bubb Road Project Initial Study/Mitigated Negative Declaration 69 November 2020 Pursuant to Section 15064.3(3) of the CEQA Guidelines, a lead agency may analyze a project’s VMT qualitatively based on the availability of transit, proximity to destinations, etc. While changes to driving conditions that increase intersection delay are an important consideration for traffic operations and management, the method of analysis does not fully describe environmental effects associated with fuel consumption, emissions, and public health. Section 15064.3(3) changes the focus of transportation impact analysis in CEQA from measuring impact to drivers to measuring the impact of driving. Future development of the site with up to three single-family residences would increase VMT due to normal vehicle usage associated with residential land uses. As noted above, bike lanes and sidewalks are available on Bubb Road, and a protected bike lane would be implemented along McClellan Road as part of the proposed project. As such, pedestrian and bicycle infrastructure are available in the project vicinity. The nearest transit stop is over one mile from the project site and, thus, public transit infrastructure accessibility is limited. However, considering the small project size and minimal daily vehicle trips, regional VMT is not anticipated to substantially increase due to implementation of the proposed project. Pursuant to the Office of Planning and Research’s Technical Advisory for SB 743, projects that generate fewer than 110 daily trips generally may be assumed to cause a less-than- significant impact related to VMT. Considering the development of up to three single- family residences that may occur following implementation of the project would generate a total of 29 ADT, the proposed project would result in a less-than-significant impact related to VMT and would not conflict or be inconsistent with CEQA Guidelines Section 15064.3(b). c,d. The proposed project would not include design features that would affect traffic safety, nor involve any incompatible uses. The project would include widening of the Krzich Place right-of-way by approximately five feet (an approximately 943-sf area) along the project frontage, which would be dedicated to the City. Each of the future single-family residences would include paved driveways, which would connect to the adjacent roadways. Thus, adequate emergency access would be provided to the site. The potential future residential uses would be considered consistent and compatible with the existing residential development in the surrounding area. As such, implementation of the proposed project would not substantially increase hazards due to design features. In addition, emergency vehicles would have reasonable access to the future residences from the existing roadways and project frontage. Based on the above, the project would not substantially increase hazards due to design features or incompatible uses, and emergency access to the site would be adequate. Therefore, the project would result in a less-than- significant impact. Bubb Road Project Initial Study/Mitigated Negative Declaration 70 November 2020 XVIII. TRIBAL CULTURAL RESOURCES. Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American Tribe, and that is: Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less- Than-Significant Impact No Impact a.

In applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe.     Discussion a,b. As discussed in Section V, Cultural Resources, of this IS/MND, the existing on-site residence is not listed or eligible for listing in the CRHR, NRHP, or in a local register of historical resources as defined in Public Resources Code section 5020.1(k), and the project site does not contain known resources that could be considered historic pursuant to the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. Furthermore, the potential for unrecorded Native American resources to exist within the project site is relatively low based on the highly-disturbed nature of the site. The City of Cupertino has not received any formal requests from local tribes for consultation pursuant to AB 52 (Public Resources Code Section 21080.3.1). As such, formal notification of the proposed project to any tribes is not required, pursuant to AB 52. Given that the project would be required to comply with the City’s standard conditions of approval regarding cultural resources, implementation of the proposed project would not result in a substantial adverse change in the significance of a tribal cultural resource, and a less-than-significant impact to tribal cultural resources would occur.

Comply with federal, state, and local management and reduction statutes and regulations related to solid waste?     Discussion a. Sewer utilities for the potential future residences on the site would be provided by the Cupertino Sanitary District, and water services would be provided by San Jose Water Company. Future development on the project site would connect sanitary sewer and water lines to existing street laterals. In addition, the project would treat all on-site runoff, and would not include direct connections to the City’s stormwater drainage facilities. Electricity and telecommunications utilities would be provided by way of connections to existing infrastructure located within the immediate project vicinity. As noted previously, natural gas infrastructure would not be provided in any new homes under the City’s all- electric reach code. Therefore, the relocation or construction of new or expanded water, wastewater treatment, stormwater drainage, or other utility infrastructure would not be required. Furthermore, given that the proposed project and possible redevelopment on the site with single-family residences would be consistent with the site’s General Plan land use and zoning designations, standard utility improvements associated with development of the site have been anticipated by the City, and associated environmental effects have been analyzed in the General Plan EIR. Therefore, the project would result in a less-than-significant impact related to the relocation or construction of new or expanded water, wastewater treatment, or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects. Bubb Road Project Initial Study/Mitigated Negative Declaration 72 November 2020 b. Water service to the project site is currently provided under contract with San Jose Water Company. Any future single-family residences on the site would connect to existing water supply infrastructure in the project vicinity. The proposed project would include demolition of the existing on-site residence. Up to three new single-family residences could potentially be developed on the project site in the future. A net increase of two residences on the project site would not substantially increase the demand for water supplies associated with the site. Given that the project and potential future development of the site with single-family residences would be consistent with the City’s General Plan land use designation, water demand associated with buildout of the project site with residential uses has been anticipated by the City and accounted for in regional planning efforts, including the UWMP. Per the UWMP, water supplies and reserves are projected to meet expected demands for normal-year and single dry-year scenarios through 2035. The Santa Clara Valley Water District anticipates facing water shortage in multiple dry-year scenarios. However, a Water Shortage Contingency Plan is in place, and a potential water supply shortage would not be a result of the proposed project. In addition, the project would comply with Chapter 14.15, Landscape Ordinance, of the City’s Municipal Code, which contains water-efficient design requirements. Therefore, sufficient water supplies would be available to serve the proposed project, and a less-than-significant impact would occur. c. Sewer service at the project site would be provided by the Cupertino Sanitary District (CSD). Any future residences on the project site would connect to the CSD’s existing sanitary sewer system by way of connections to existing sewer lines. The CSD collection system directs wastewater to the San Jose/Santa Clara Water Pollution Control Plant (SJ/SCWPCP), a joint powers authority. The project area is currently provided sewer services by the CSD, including the existing on-site residence. The proposed project would include demolition of the existing residence. Up to three new single-family residences could potentially be developed on the project site in the future. A net increase of two residences on the project site would not substantially increase the demand for wastewater treatment associated with the site, and would not affect the available capacity of the SJ/SCWPCP. In addition, the proposed project and potential future development of the site with single-family residences would be consistent with the site’s current General Plan land use and zoning designations. Thus, increased demand for wastewater collection and treatment facilities associated with buildout of the site have been anticipated by the City and analyzed in the General Plan EIR. Based on the above, the City would have adequate capacity to serve the proposed project in addition to the City’s existing commitments, and a less-than-significant impact would occur. d,e. The City contracts with Recology South Bay (Recology) for solid waste collection services. All non-hazardous solid waste collected under the Recology franchise agreement is taken to Newby Island Sanitary Landfill for processing. Under the agreement, recyclable materials also are handled by Recology. Of the 27,593 tons of solid waste disposed in 2012, 25,440 tons, or 92 percent was disposed of at the Newby Island Landfill. The Monterey Peninsula Landfill, the Guadalupe Sanitary Landfill, and the Altamont Landfill and Bubb Road Project Initial Study/Mitigated Negative Declaration 73 November 2020 Resource Recovery Facility accepted the next highest amounts of waste from Cupertino, respectively receiving 1,260 tons (4.6 percent of total), 321 tons (1.2 percent) and 238 tons (0.9 percent) of all waste. Per the General Plan EIR, sufficient landfill capacity is available to serve buildout of the General Plan. The project site is currently developed with residential use and is designated as Low Density in the City’s General Plan. The proposed project would demolish the existing on- site residence and allow for the potential future construction of up to three new single- family residences. The net increase of two residences on the project site would not substantially increase the solid waste generation associated with the site. In addition, the proposed project and potential future development of the site with single-family residences would be consistent with the General Plan land use designation for the site. As such, generation of solid waste associated with the project site has been previously anticipated by the City. Based on the above, the project would not increase solid waste generation such that the capacity of any landfills serving the City would be exceeded. In addition, construction and any demolition debris associated with the project would be subject to Chapter 16.72 of the City’s Municipal Code, which requires that a minimum of 60 percent of construction and demolition debris be diverted from a landfill. Therefore, the proposed project would be served by a landfill with sufficient permitted capacity to accommodate the project’s solid waste disposal needs and would comply with federal, State, and local statutes and regulations related to solid waste. Accordingly, a less-than-significant impact would occur. Bubb Road Project Initial Study/Mitigated Negative Declaration 74 November 2020 XX. WILDFIRE.

According to the CAL FIRE Fire and Resource Assessment Program, the project site is not located within or near a state responsibility area or lands classified as a Very High Fire Hazard Severity Zone.35 In addition, the site is currently developed and surrounded by existing development. The developed nature of the area surrounding the project site precludes the spread of wildfire to the site. Furthermore, while not located in an area of high wildfire risk, the future development on the project site would be required to include adequate fire protection features, such as fire alarms/smoke detectors, as required by State law. Therefore, the proposed project would not be expected to be subject to or result in substantial adverse effects related to wildfire, and a less-than-significant impact would occur. 35 California Department of Forestry and Fire Protection. Santa Clara County, Very High Fire Hazard Severity Zones in LRA. October 8, 2008. Bubb Road Project Initial Study/Mitigated Negative Declaration 75 November 2020 XXI. MANDATORY FINDINGS OF SIGNIFICANCE. Potentially Significant Impact Less-Than- Significant with Mitigation Incorporated Less-Than- Significant Impact No Impact a. Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory?     b. Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)?     c. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly?     Discussion a. As described throughout this IS/MND, impacts related to special-status plants and cultural resources would be less than significant. In addition, potential impacts related to reducing the habitat for nesting migratory birds would be reduced to less-than-significant levels with implementation of the mitigation measures required by this IS/MND, as well as compliance with General Plan policies and all applicable sections of the Municipal Code. As such, implementation of the proposed project, as well as the potential future redevelopment of the site with up to three single-family residences would not: 1) degrade the quality of the environment; 2) substantially reduce or impact the habitat of fish or wildlife species; 3) cause fish or wildlife populations to drop below self-sustaining levels; 4) threaten to eliminate a plant or animal community; 5) reduce the number or restrict the range of a rare or endangered plant or animal; or 6) eliminate important examples of the major periods of California history or prehistory. Therefore, a less-than-significant impact would occur. b. The proposed project, which would allow for the potential future construction of up to three new single-family homes on the project site, in conjunction with other development within the City of Cupertino could incrementally contribute to cumulative impacts in the area. However, as demonstrated in this IS/MND, all potential environmental impacts that could occur as a result of project implementation would be reduced to a less-than-significant level with implementation of project-specific mitigation measures, as well as compliance with applicable General Plan policies and Municipal Code standards. In addition, the site has been anticipated by the City for residential development. Thus, future buildout of the site with residential uses was considered in the cumulative analysis of buildout of the General Plan. When viewed in conjunction with other closely related past, present, or reasonably foreseeable future projects, the proposed project and potential future development of the Bubb Road Project Initial Study/Mitigated Negative Declaration 76 November 2020 site with single-family residences would not substantially contribute to cumulative impacts in the City of Cupertino, and the project’s cumulative impact would be less than significant. c. As described in this IS/MND, construction workers and/or potential future occupants at the project site could be exposed to existing soil contaminants. In addition, without implementation of appropriate safety measures, the proposed project could potentially expose construction workers during demolition activities to LBP and asbestos-containing materials. However, the proposed project would be required to implement the project- specific mitigation measures within this IS/MND, as well as comply with all applicable General Plan policies and standard conditions of approval, which would ensure that any potential direct or indirect effects to human beings would be reduced to less-than- significant levels. Therefore, the proposed project would have a less-than-significant impact.

EXECUTIVE SUMMARY A Phase I Environmental Site Assessment has been conducted for the Property. The Findings, Opinion, and Conclusions are provided below: The Property is located at 11226 Bubb Road, Cupertino, CA 95014. The Property is identified by its APN(s) as 36206036. The Property is currently single-family residence. The Property was not listed in the EDR Report, in the FINDS and SLIC databases. Please refer to Section 5.4 of this report for additional details. The EDR Report was reviewed for any adjoining and/or surrounding sites which may pose a risk of significant environmental concern to the Property. There were no adjoining or surrounding sites of potential concern identified in the surrounding area. The Orphan Site List was reviewed. No sites were listed on the Orphan List that were within the search radius of the Property. Based on the aerial photos, topographic maps, and City Directory listings of the site, in addition to information obtained while conducting interviews, the Property was developed as part of an orchard sometime before 1948 and was redeveloped in 1955 with the present -day residential structure. An addition/remodel was permitted in the 1980’s. Historical use of the site includes, but is not limited to, orchards and a residence. Interviews were conducted with individuals and local government agencies in an attempt to obtain any information indicating Recognized Environmental Conditions in connection with the Property. Please refer to Section 7 of this report for additional details on these interviews. Enviro Assessment personnel identified no significant observable contaminated areas on the Property during the site reconnaissance. Page 6 November 17, 2017 Project Number 2017-11 -008 © ENVIRO ASSESSMENT, PC ENVIRONMENTAL ∙ ENGINEERING ∙ GEOLOGY PO BOX 1154, BONNERS FERRY, ID 83805 PHONE (844)-742-7311 (844-PHASE11) FAX (877) 623-5493 All available standard historical sources have been reviewed in an attempt to identify the likelihood of past uses of the Property and surrounding area, having led to Recognized Environmental Conditions (RECs) in connection with the site. No significant environmental concerns have been identified based on the historical use of the Property or surrounding area, with the exception of the historical use of the Property and surrounding area as orchards. This is discussed further in the interview paragraph within this section, below. The Property was listed in the EDR Report. RESIDENCE – 11226 BUBB RD was listed in the FINDS and SLIC databases. The SLIC database lists this as a cleanup program site with an open site assessment status as of May, 2015. According to a 2015 notification from the County of Santa Clara DEH found via the database’s GeoTracker link, prior to the development of the residential structure in 1955, the site consisted of orchards. Soil sampling performed at the site revealed soils impacted with certain organochlorine pesticides above the residential EPA Regional Screening Levels. This is discussed further in the interview paragraph within this section, below. The EDR Report was reviewed for any adjoining, surrounding, or Orphan sites which may pose a risk of significant environmental concern to the Property. Based on the description of the cases, the type of database listings, the amount of past regulatory oversight, and the relative distances to the Property, the sites listed are not anticipated to impact the Property at this time. Enviro Assessment personnel did not observe any visible RECs related to the Property. No significant environmental concerns were identified during the interviews conducted for the Property, with the exception of the following: Previous Phase I and Phase II Environmental Assessments were performed in 2013 and 2014, respectively. The Phase II revealed minor contaminants found around the perimeter of the residential structure onsite. Conclusions and recommendations stated that “results of this evaluation demonstrate that a human health cancer risk above DTSC’s decision-making threshold and a noncancer hazard index above the target hazard index were found to be associated with the Page 7 November 17, 2017 Project Number 2017-11 -008 © ENVIRO ASSESSMENT, PC ENVIRONMENTAL ∙ ENGINEERING ∙ GEOLOGY PO BOX 1154, BONNERS FERRY, ID 83805 PHONE (844)-742-7311 (844-PHASE11) FAX (877) 623-5493 site. The 95th percentile blood lead level estimate associated with the maximum detected lead concentration was found to be below the target child blood lead level. Except where noted above, the areas contributing to the elevated risk and hazard have been identified. Based on the findings of this investigation, a minor response actions at several locations is recommended.” The Phase II recommended response was to remove soil within three feet of the structure’s foundation to a depth of one foot and dispose of the soil; and to also remove the soil from under the structure after it’s demolition to the same depth. There is an Update to Phase II Environmental Site Assessment letter, dated November 17, 2017, which recommends the same response. Please refer to the GeoTracker database findings, below, for additional discussion. Documents found in the GeoTracker database revealed pre-redevelopment assessments in 2015 found soils to be impacted with organochlorine pesticides that were above residential EPA Regional Screening Levels. The impact was determined to be due to the Property’s historical use as orchards. The presence of pesticides above screening levels in the soils on site constitutes a REC. Enviro Assessment has performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM International Standard E1527-13 practice for the Property located at 11226 Bubb Road, Cupertino, CA 95014. The Property is identified by its APN(s) as 36206036. Any exceptions to, or deletions from, this practice are described in the Limitations Section of this report. This assessment has revealed no evidence of Recognized Environmental Conditions in connection with the Property., with the exception of the presence of pesticides and metals above screening levels in the soils due to the Property’s historical use as orchards. 2. INTRODUCTION 2.1 Purpose The purpose of this Phase I Environmental Site Assessment is to identify, to the extent feasible, Recognized Environmental Conditions (REC) in connection with the Property. The report follows Page 8 November 17, 2017 Project Number 2017-11 -008 © ENVIRO ASSESSMENT, PC ENVIRONMENTAL ∙ ENGINEERING ∙ GEOLOGY PO BOX 1154, BONNERS FERRY, ID 83805 PHONE (844)-742-7311 (844-PHASE11) FAX (877) 623-5493 the processes prescribed by the AAI rule and in ASTM International Standard E1527-13, Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. As defined by ASTM International E1527-13, §1.1.1, the term "Recognized Environmental Conditions" refers to: The presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions. 2.2 Detailed Scope-of-Service The scope of work performed for this Phase I Environmental Site Assessment report includes: • Collecting and reviewing available environmental related information concerning the Property and other data pertinent to the specific site per the ASTM International Standard E1527-13; • Conducting a site visit to observe current site uses, observe adjacent land use, and gather data on possible spills, or misuse of chemicals that could be considered a REC; • Contacting appropriate regulatory personnel, and reviewing regulatory files regarding the Property in question. No additional non-scope considerations per Section 13 of the ASTM International Standard E1527- 13 were included in this Phase I Environmental Assessment report. 2.3 Significant Assumptions No significant assumptions were made in this assessment. 2.4 Limitations and Exceptions Limitations This report is applicable only for the project and site studied.

The EDR Report was reviewed for any adjoining, surrounding, or Orphan sites which may pose a risk of significant environmental concern to the Property. Based on the description of the cases, the type of database listings, the amount of past regulatory oversight, and the relative distances to the Property, the sites listed are not anticipated to impact the Property at this time. Enviro Assessment personnel did not observe any visible RECs related to the Property. No significant environmental concerns were identified during the interviews conducted for the Property, with the exception of the following: • Previous Phase I and Phase II Environmental Assessments were performed in 2013 and 2014, respectively. The Phase II revealed minor contaminants found around the perimeter of the residential structure onsite. Conclusions and recommendations stated that “results of this evaluation demonstrate that a human health cancer risk above DTSC’s decision-making threshold and a noncancer hazard index above the target hazard index were found to be associated with the site. The 95th percentile blood lead level estimate associated with the maximum detected lead concentration was found to be below the target child blood lead level.

Based on the findings of this investigation, a minor response actions at several locations is recommended.” The Phase II recommended response was to remove soil within three feet of the structure’s foundation to a depth of one foot and dispose of the soil; and to also remove the soil from under the structure after it’s demolition to the same depth. There is an Update to Phase II Environmental Site Assessment letter, dated November 17, 2017, which recommends the same response. Please refer to the GeoTracker database findings, below, for additional discussion. • Documents found in the GeoTracker database revealed pre-redevelopment assessments in 2015 found soils to be impacted with organochlorine pesticides that were above residential EPA Regional Screening Levels. The impact was determined to be due to the Property’s historical use as orchards. The presence of pesticides above screening levels in the soils on site constitutes a REC. 10.

The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

The types of land use restriction include deed notice, deed restriction, or a land use restriction that binds current and future owners.

Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

Yes, this case would be similar to the one that we oversaw on McClellan for Ms. Suejane Han. I think I worked with George from your office on that one. The area around the tree was difficult and we had to have discussions about possibly losing the tree. I have attached the application for entry into our Voluntary Cleanup Program. Have the applicant complete the application and submit to me. Can you modify MM HAZ – 1.5 to state “…shall adhere to the procedures identified in” a Site Mitigation Plan for Soil Management during Construction that has been approved by the oversight agency… The way this paragraph is currently written sounds like a plan has already been written. If upon our review the document is found to be insufficient in any manner, we would require modification prior to approval. But I do see in a lower paragraph language about preparation and approval of such a document.

Our findings are summarized below. Because of past agricultural use, soil testing was undertaken at 11226 Bubb Road to determine if residual concentrations of persistent agricultural chemicals, such as organochlorine pesticides and metals, are present on the site. Several chemicals were detected on the site including arsenic, lead, chlordane, dichlorodiphenyldichloroethane (4, 4-DDD), dichlorodiphenyldichloro-ethylene (4,4’- DDE), 4,4’-dichlorodiphenyltrichloroethane (4,4’-DDT), dieldrin, heptachlor, heptachlor epoxide, and methoxychlor. The levels of chemicals on the site were compared to California Human Health Screening Levels (CHHSLs), which provide a risk-based determination of environmental concerns on a potentially contaminated property. CHHSL thresholds were last revised by the Office of Environmental Health Hazard Assessment (OEHHA) in 2009 and 2010. These thresholds are not regularly updated based on the most recent data. For this reason, in 2014 the Department of Toxic Substances Control (DTSC) switched from CHHSLs to Regional Screening Levels (RSLs) to evaluate risks from hazardous materials to human health. RSLs were established by the US Environmental Protection Agency (USEPA) and are updated regularly, typically at least twice per year. The Phase II ESA that was prepared for the project at 11226 Bubb Road, compares the detected contaminants to CHHSLs which are no longer the DTSC recommended thresholds for evaluating risks to human health. We recommend the contaminant levels on the site be re-evaluated based on RSLs, consistent with the most recent methodologies used in the Bay Area to evaluate hazardous materials risks to human health.1 Regardless of the thresholds used (CHHSLs versus RSLs), based on the Phase II ESA it appears that hazardous materials are present on the site and remediation will be required for the proposed residential uses. Oversight for characterization and remediation of unauthorized releases of 1 The San Francisco Bay Regional Water Quality Board has also established screening levels for a range of hazardous substances in soil, groundwater, and soil vapor. These environmental screening levels (ESLs) are commonly employed by the Regional Board to assess whether potential hazards may be present on a site. 2 pollutants on properties in Cupertino may be handled by one or more regulatory agencies. These include the San Francisco Bay Regional Water Quality Control Board, County of Santa Clara Department of Environmental Health, or DTSC. From a California Environmental Quality Act (CEQA) perspective, if there is known or potential contamination above screening levels used for residential uses by oversight agencies, enough characterization needs to be done to come up with a mechanism for mitigation to reduce possible exposure of future residents (and construction workers, if concentrations are higher) that could result in substantial health risks. The mitigation measures would identify if additional sampling and analysis is required, remediation standards, the types of controls that may be employed (e.g., institutional or engineering controls as defined by oversight agencies), oversight for characterization and any remediation, and timing (e.g., prior to construction grading). On residential sites, risks are generally reduced either by remediation of contaminated soils (e.g., excavation and off-site disposal) and/or implementation of engineering and institutional controls (e.g., soil capping and deed restrictions/notices) to ensure that any potential added health risks to construction workers, maintenance and utility workers, residents, and the general public are reduced to acceptable levels. If contamination above levels of concern are present, generally enough sampling needs to be done to complete a Work Plan or Site Management Plan for remediation or soil handling and determine the approximate depth of any soil removal. One of the regulatory agencies would provide oversight on any soil removal and the collection and analysis of confirmation samples. The oversight agencies can also provide a clearance letter to the City that the Work Plan had been completed and/or there were adequate controls in place to reduce health risks to residents to a less than significant level. For your information, below are two examples of mitigation measures for residential development where residual pesticide concentrations were detected at levels exceeding thresholds. 20840 McClellan Road Mitigated Negative Declaration (July 2013) Mitigation Measures: As a condition of approval and in conformance with local, state, and federal regulations, the project shall implement the following mitigation measures with the oversight of the Santa Clara County Department of Environmental Health and City of Cupertino to reduce impacts associated with redevelopment of the site to a less than significant level: MM HAZ – 1.1: The project shall excavate the area of lead-impacted soil to a depth of 1.5 feet in the area identified in the Revised Site Mitigation Plan. Soils will be tested, profiled, and granted acceptance to a landfill permitted to handle disposal of lead contaminated soil prior to excavation of these soils directly into trucks for offhaul from the site. Dust control measures (watering) shall be employed prior to and during excavation and loading to eliminate or minimize dust creation. MM HAZ – 1.2: From the rear of the existing residence to the midpoint of the property, pesticide-impacted soils that would be located beneath pavement or covered by structures will be excavated to a depth of six inches and disposed of at a permitted landfill. Where impacted soils are present in future landscape areas, soils will be excavated to a depth of one foot below grade. In planned landscape areas, confirmation sampling will be completed to confirm pesticide-impacted soils have been removed. Contaminated soils from landscape areas up to a depth of six inches will be disposed of offsite. The 3 remaining excavated landscape area soil from depths of six inches to one foot will be stockpiled on-site and eventually disposed at a permitted landfill or placed as fill beneath areas of pavement. MM HAZ – 1.3: Within the branch canopy of the large oak tree on-site surface soil to a depth of approximately six to twelve inches below grade, will be excavated by hand under the consultation and direction of the City of Cupertino’s arborist. Prior to excavation, confirmation subsurface samples will be collected at three-inch intervals from six inches to one foot below grade and analyzed to establish excavation depths within the oak tree canopy. Confirmation sampling will be completed to confirm pesticide-impacted soils have been removed. MM HAZ – 1.4: In the event confirmation samples reveal the presence of additional lead or organochlorine pesticides, additional excavation and sampling will be completed under the oversight of the Santa Clara County Department of Environmental Health. MM HAZ – 1.5: Remediation work on the site shall adhere to the procedures identified in the Site Mitigation Plan for Soil Management during Construction, including off- site disposal, dust control, reuse of on-site soils, and implementation of a contractor health and safety plan. (Less Than Significant Impact with Mitigation Incorporated) 990 Wren Avenue Initial Study City of Santa Clara (January 2015) MM HAZ-1.1: As pesticide contaminated soils were found on the site in concentrations above established thresholds (e.g., Regional Water Quality Control Board ESLs for unrestricted residential use), regulatory oversight shall be initiated and a Site Management Plan (SMP) will be prepared and implemented (as outlined below). Regulatory oversight may be provided by the Santa Clara County Department of Environmental Health (SCCDEH), the Regional Water Quality Board (RWQCB) or DTSC. These agencies may also require additional site investigation to fully delineate the extent of contaminants of concern at the site. The potential risks to human health shall be reduced either by remediation of contaminated soils (e.g., excavation and off-site disposal) and/or implementation of engineering and institutional controls (e.g., soil capping and deed restrictions/notices) to ensure that any potential added health risks to construction workers, maintenance and utility workers, residents, and the general public as a result of potential hazardous materials contamination are reduced to acceptable levels, as required by a regulatory oversight agency. Any contaminated soils removed shall be disposed of according to the California Hazardous Waste Regulations. Contaminated soil shall be handled by trained personnel using appropriate protective equipment and engineering and dust controls, in accordance with local, State, and Federal laws. The contaminated soil to be removed from the site shall be hauled off-site and disposed of at a licensed hazardous materials disposal site. 4 Institutional and engineering controls employed on the site may include placement of new fill, pavement, or buildings over contaminated soils and/or adoption of deed restrictions. An SMP will be prepared to establish management practices for handling impacted soil material that may be encountered during site development and soil-disturbing activities. Components of the SMP will include: a detailed discussion of the site background; preparation of a Health and Safety Plan by an industrial hygienist; notification procedures if previously undiscovered significantly impacted soil is encountered during construction; on-site soil reuse guidelines based on the California RWQCB, San Francisco Bay Region’s reuse policy; sampling and laboratory analyses of excess soil requiring disposal at an appropriate off-site waste disposal facility; a dust control plan; and soil stockpiling protocols. Prior to issuance of grading permits, a copy of the SMP must be approved by the SCCEHD, the City’s Director of Planning and Inspection, and the Santa Clara Fire Chief. Implementation of the identified mitigation measures would reduce the risk of construction worker and resident exposure to contaminated soils to a less than significant level.

INTRODUCTION As requested, Enviro Assessment, PC (Enviro Assessment) has prepared an Update to the Original Phase II Environmental Site Assessment (Update) for 11226 Bubb Road, Cupertino, CA 95014. The Property is identified by its APN(s) as 36206036. For the purpose of this Update, the term “Property” shall refer to either one property or multiple properties. The purpose of the Update is to address and compare laboratory results from the Phase II investigation conducted August 28, 2014 and update site characterization recommendations. 2. SITE HISTORY A previous Phase I Environmental Site Assessment was performed in July of 2013. Based on the aerial photos, internet research, and topographic maps of the site, the Property was developed with the current single-family residence in 1955. Prior to the single-family residence that occupies the Property now, the Property and much of the surrounding area were agricultural. Agricultural was the first known use of the Property. An addition or remodel was permitted in 1980. No other records were found for the Property. Along with the Phase I Environmental Site Assessment, a Phase II Investigation was conducted in July 2014. The purpose of the Phase II was to determine the presence of impacts to the soil from the past use as agricultural and residential land. Page 4 November 17, 2017 Project Number 2017-11 -009 © ENVIRO ASSESSMENT, PC ENVIRONMENTAL ∙ ENGINEERING ∙ GEOLOGY PO BOX 1154, BONNERS FERRY, ID 83805 PHONE (877) 742-7311 FAX (877) 623-5493 3. POTENTIAL ISSUES Agricultural Use Based on aerial photographs reviewed, it appears that the site (a total of ¾ acres) was used as an orchard since prior to 1948 until the residence was constructed in 1955. Structures Structures constructed prior to 1978 may have been painted with lead-based paints. Organochlorine Pesticides (OCPs) may have been applied as pest control to properties prior to 1988. One residence was constructed in 1955 at 11226 Bubb Road based on information gathered during the Phase I Environmental Site Assessment (EA, 2013). Based on the construction date cited above, lead-based paints could have been used at the structure. Based on the construction dates, OCPs could have been used on the Property, based on typical pest control usage. Sampling Strategy The 2014 investigation was intended as a screening-level tool to determine whether Organochlorine Pesticides (OCPs) and CAM 17 metals related impacts to the Property exist. DTSC Guidelines recommended 16 discrete samples across the entirety of the Property including the crawlspace of the residence, under concrete, and within two feet of existing structures Laboratory Results The tables below present the laboratory results as reported by Cal Labs Inc. (formerly Argon). The complete August 28, 2014 Phase II report with laboratory results is attached. The Direct Exposure Human Health Risk Levels (Table S-1) from the California Water Boards Environmental Screening Levels (Feb. 2016 Rev. 3) were reviewed for each chemical for soil being used for residential shallow soil exposure. Screening Levels provide a risk-based determination of environmental Page 5 November 17, 2017 Project Number 2017-11 -009 © ENVIRO ASSESSMENT, PC ENVIRONMENTAL ∙ ENGINEERING ∙ GEOLOGY PO BOX 1154, BONNERS FERRY, ID 83805 PHONE (877) 742-7311 FAX (877) 623-5493 concerns on a potentially contaminated property. Note that the lab reports concentrations in parts per million (mg/kg). The samples are summarized in the following tables.

CHEMICALS OF POTENTIAL CONCERN Based upon the above descripted comparison, arsenic, cobalt, lead, chlordane, and dieldrin are chemicals of potential concern. Arsenic As shown in Table 3 (Appendix), no metals of concern were detected in concentrations exceeding the screening levels, with the exception of Arsenic. However, based on regional background soil sampling results from the Wilson Etal study (Wilson, S. A. Etal, Analysis of Soil Samples from the San Joaquin Valley of California, United States Geological Survey (USGS), Open File Report 90 214, undated), the Arsenic levels do not appear to be elevated above typical levels in California, with the exception of the sample “R Front Corner”. Metals Cobalt and Lead are identified as above the respected ESLs. OCPs Chlordane and dieldrin are identified as above the respected ESLs. 5. SUMMARY AND OPINION The Property is located at 11226 Bubb Road, Cupertino, CA 95014. The Property is identified by its APN(s) as 36206036. The purpose of the Phase II was to evaluate the soil of the Property for impacts from the site’s historical use a residence and as part of an orchard. The soils samples collected and analyzed indicated elevated levels of arsenic, cobalt, lead, chlordane, and dieldrin. These samples indicate that soils around the residential structure are impacted with metals and OCPs at levels above the ESLs identified by the state. 6. CONCLUSIONS AND RECOMMENDATIONS It is recommended that the minor contamination at the following locations be cleaned up by the Property owner: • Soil adjacent (within 3 feet) to the foundation along the front of the house should be Page 10 November 17, 2017 Project Number 2017-11 -009 © ENVIRO ASSESSMENT, PC ENVIRONMENTAL ∙ ENGINEERING ∙ GEOLOGY PO BOX 1154, BONNERS FERRY, ID 83805 PHONE (877) 742-7311 FAX (877) 623-5493 removed to a depth of 1 foot and disposed of (chemicals of concern: chlordane, dieldrin, and arsenic) • After demolition of the house, the soil within the foundation should be removed and disposed of to a depth of 1 foot (chemicals of concern: cobalt, lead, and chlordane) Special Terms and Conditions We have been authorized by Ray Chen to update the original Phase II environmental site assessment of the Property.
